Question

For a school play you are making plastic use that are 3.5 feet on each side.How much plastic is needed to make one cube? if you want to make two cubes how much plastic is needed?

Answer 1

Answer:

one cubes: 73.5 ft²

two cubes: 147 ft²

Step-by-step explanation:

Using plastic to construct a cube means finding the surface area of the figure.  The general formula for the surface area of a cube is:

SA = 6s², where 's' is the measure of one side.

Since one side is 3.5 feet:

SA = 6(3.5)² = 73.5 ft² per cube

Two cubes: 73.5 x 2 = 147 ft²
