1. March 2, Math 102
OBJECTIVE: Students will be able to calculate the volume of prisms and cylinders, using a given formula and a calculator
AIM: How is volume different from surface area?
STANDARDS: 7.G.2
PRIOR KNOWLEDGE: Find the area of a rectangle with a length of 12 cm and a width of 8 cm

2. MINILESSON
The number of cubes that fit into a solid figure (a three dimensional figure) gives the measure of its volume in cubic units.
Examples
cubic centimeters cm3
cubic feet ft3
cubic inch in3

3. V = 5 x 3 x 4 Find the volume of this rectangular prism V = l x w x h

4. Find the volume of the cylinder below
r = 4 cm
V = πr2h
= (3.14)(16)(20)
= 1,004.8 cm3
20 cm

5. V = l x w x h V = πr2h INDEPENDENT WORK
Use the formulas to find the volume of the prism and the cylinder
d = 12 in
6 in
18 in
4 in
7 in
V = l x w x h V = πr2h

6. V = l x w x h V = πr2h HOMEWORK
Use the formulas to find the volume of the prism and the cylinder (Use a calculator for this homework)
(Use 3.14 for π)
d = 12 in
8.5 cm
24.4 in
5 cm
9.6 cm
V = l x w x h V = πr2h
