Answer 1

Answer:

$27

Step-by-step explanation:

The dimensions of the sandbox (that is a rectangular prism) are 3m x 2m x 1m.

We need to first find the volume of the sandbox.

The volume of a rectangular prism is:

V = L * W * H

where L = length

W = Width

H = height

The volume of the sandbox is:

V = 3 * 2 * 1 = $6 m^3$

Sand for the sandbox costs $4.50 per cubic meter.

The cost to completely fill the sandbox is:

4.50 * 6 = $27
