40 Create a 3-D shape that has a volume of 8 cm 3 and a surface area of 24 cm 2. What does this shape look like? 5 pt

41 This 3-D shape has a volume of 8 cm 3 and 24 cm 2. The dimensions of this prism are : 2 x 2 x 2. 5 pt

42 1 pt Which of these flat patterns will not completely cover a unit cube (A unit cube is one single cube)?

43 1 pt These 4 shapes will not cover a unit cube.

44 2 pt What are the dimensions of the resulting prism after folding the flat pattern into a prism?

45 2 pt 4 units 3 units 4 x 3 x 3 are the dimensions (in any order)

46 3 pt A company wants to find the cheapest way to box its products. The latest product they have designed needs 30 cubic units of space. Give the dimensions of the box that requires the least amount of packaging material (surface area) First find all the ways to make a prism with 30 cubes. There are 4 ways. Hint: make a chart.

47 3 pt The following boxes all have a volume of 30 cubic units. Notice all the dimensions are FACTORS of x 1 x 30 1 x 2 x 15 1 x 3 x 10 1 x 5 x 6 2 x 3 x 5 The 2 x 3 x 5 box requires the least amount of packaging material because it is the shape that looks most like a cube.

48 When put together, what is the volume of this figure? 4 pt

49 52 units 3 16 units 3 12 units 3 4 pt

50 5 pt Give the list of boxes that have a volume of 40 cubic units. (hint: there are 6 possibilities)

51 5 pt The following boxes all have a volume of 40 cubic units. Notice that all the dimensions are FACTORS of 40 and when you multiply the dimensions you always get an answer of x 1 x 40 1 x 2 x 20 1 x 4 x 10 1 x 5 x 8 2 x 2 x 10 2 x 4 x 5
