VOLUME OF PRISMS

LESSON 6.3 RECALL VOLUME OF A RECTANGULAR PRISM: V = lwh sometimes “B” is used for lw in the example V = Bh. Both are the same.

LESSON 6.3 RECALL VOLUME OF A RECTANGULAR PRISM: V = lwh 3 cm length

LESSON 6.3 RECALL VOLUME OF A RECTANGULAR PRISM: V = lwh 7 cm width 3 cm length

LESSON 6.3 RECALL VOLUME OF A RECTANGULAR PRISM: V = lwh 5 cm height 7 cm width 3 cm length

LESSON 6.3 RECALL VOLUME OF A RECTANGULAR PRISM: V = lwh V = 3 x 7 x 5 = 105 cm 3 5 cm height 7 cm width 3 cm length

LESSON 6.3 RECALL VOLUME OF A RECTANGULAR PRISM: V = lwh V = 3 x 7 x 5 = 105 cm 3 5 cm height 7 cm width 3 cm length Volume is measured in units cubed

LESSON 6.3 RECALL Area = l w A = 21 cm 2 3 cm length 7 cm width Area is measured in units 2

LESSON 6.3 RECALL Area = l w A = 21 cm 2 Volume = l w h V = 1 05 cm 3 3 cm length 7 cm width 5 cm height 3 cm length 7 cm width Volume is measured in units 3 Area is measured in units 2

LESSON 6.3 UNDERSTAND FIRST I WILL __________________________________________________ _______________________________________________________________ NEXT I WILL __________________________________________________ ______________________________________________________________ THEN I WILL __________________________________________________ _______________________________________________________________

LESSON 6.3 UNDERSTAND FIRST I WILL ___Multiply the length, width and height of the prism _______________________________________________________________ NEXT I WILL __________________________________________________ ______________________________________________________________ THEN I WILL __________________________________________________ _______________________________________________________________

LESSON 6.3 UNDERSTAND FIRST I WILL ___Multiply the length, width and height of the prism _______________________________________________________________ NEXT I WILL _Write the answer in units cubed (in 3, cm 3, ft 3 ) _____ ______________________________________________________________ THEN I WILL __________________________________________________ _______________________________________________________________

LESSON 6.3 APPLY is equal to 10 x 12 or 120 length = 2 mm width = 4 mm height = 8 mm volume = 64 mm 3 4 mm 6 mm 2 mm

LESSON 6.3 APPLY is equal to 10 x 12 or 120 length = 2 mm width = 4 mm height = 8 mm volume = 64 mm 3 4 mm 6 mm 2 mm

LESSON 6.3 APPLY is equal to 10 x 12 or 120 length = 2 mm width = 4 mm height = 8 mm volume = 64 mm 3 4 mm 6 mm 2 mm

LESSON 6.3 APPLY is equal to 10 x 12 or 120 length = 2 mm width = 4 mm height = 8 mm volume = 64 mm 3 4 mm 6 mm 2 mm

LESSON 6.3 APPLY is equal to 10 x 12 or 120 length = 2 mm width = 4 mm height = 8 mm volume = 64 mm 3 4 mm 6 mm 2 mm

LESSON 6.3 APPLY is equal to 10 x 12 or 120 length = 2 mm width = 4 mm height = 6 mm volume = 64 mm 3 4 mm 6 mm 2 mm

LESSON 6.3 APPLY is equal to 10 x 12 or 120 length = 2 mm width = 4 mm height = 6 mm volume = 64 mm 3 4 mm 6 mm 2 mm

LESSON 6.3 APPLY is equal to 10 x 12 or 120 length = 2 mm width = 4 mm height = 6 mm volume = 48 mm 3 4 mm 6 mm 2 mm HINT!!! JUST MULTIPLY ALL THE NUMBERS TOGETHER

LESSON 6.3 APPLY What is the volume? Area is equal to 10 x 12 or 120 Volume = l w h 2 cm 3 cm

LESSON 6.3 APPLY What is the volume? g V = 18 cm 3 Volume = l w h 2 cm 3 cm

LESSON 6.3 APPLY What is the volume? equal to 10 x 12 or 120 V= l w h 10 cm 8 cm 2 cm

LESSON 6.3 APPLY What is the volume? equal to 10 x 12 or 120 V= l w h V = 160 cm 3 10 cm 8 cm 2 cm

LESSON 6.3 ANALYZE Which figure represents 189 in 3 ? 6 in 2 in 6 in 7 in 9 in 4 in 9 in 2 in 8 in 3 in 6 in 4 in

LESSON 6.3 EVALUATE What is the width of this rectangular prism if the volume is 343 cm 3 ? 7 cm ? cm

LESSON 6.3 CREATE Construct a rectangular prism that would equal to 216 in 3 ? Area of triangle is 7 x 2 or 14 in 2 Area of rectangle is 5 x 2 or 10 in 2 Total area is 24 in 2 2 in 3 in 2 in 9 in 8 in 3 in 8 in 3 in 8 in A B C D E F

Ok Let’s Practice

Let’s Practice (easy) What is the voIume? length: 18 cm width: 10 cm height: 7 cm Volume: 1260 cm 3

Let’s Practice (easy) What is the voIume? length: 18 cm width: 10 cm height: 7 cm Volume: 1260 cm 3

Let’s Practice (medium) What is the area and voIume? length: 12 in width: 5 in height: 7 in Area is 60 in 2 and Volume is : 420 in 3

Let’s Practice (medium) What is the area and voIume? length: 12 in width: 5 in height: 7 in Area is 60 in 2 and Volume is 420 in 3

Let’s Practice (challenging) What is the voIume? V = 360 ft 3 2 x + 8 ft 5 2 – 10 ft x = 2 ft

Let’s Practice (challenging) What is the voIume? V = 360 ft 3 2 x + 8 ft 5 2 – 10 ft x = 2 ft

Let’s Practice (nasty) What is the voIume? 2p + 5 – (3 x 6) if p =9 4(18 – 2 3 ) – |7| 4

Let’s Practice (nasty) What is the voIume? V = 420 units 3 2p + 5 – (3 x 6) if p =9 4(18 – 2 3 ) – |7| 4

GREAT JOB!!!
