My mom built a new sandbox that is 3 \text { m}3 m3, start text, space, m, end text long, 2 \text { m}2 m2, start text, space, m, end text wide, and 1 \text { m}1 m1, start text, space, m, end text high for my sister and me. Sand for the sandbox costs \$4.50$4.50dollar sign, 4, point, 50 per cubic meter. How much will it cost to completely fill the sandbox with sand? \$$dollar sign

$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 =

Sand for the sandbox costs $4.50 per cubic meter.

The cost to completely fill the sandbox is:

4.50 * 6 = $27
