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?

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

b

step-by-step explanation:

a difference is the result of subtraction. while each of these expressions has subtraction in it, a difference will be the result when subtraction is the last operation applied in the order of operations for the expression. this means subtraction must be outside of the parenthesis. only b has this.
