Question

You are creating concrete planters for a

garden border by placing the concrete in a large
cube and then placing a smaller cube inside. The
amount of concrete you need can be found using
the expression - y where is the volume of the
larger cube and v is the volume of the smaller
cube. How much concrete do you need to make
one planter?​

Answer 1

2044 cubic inches

Explanation:

The amount of concrete required is the larger volume MINUS the smaller volume.

Note: Volume of cube = s^3 where s is the side length

Larger Volume = s^3 = 15^3 = 3375

and

Smaller Volume = s^3 = 11^3 = 1331

Hence, amount of concrete needed to make 1 planter = 3375 - 1331 = 2044 cubic inches
