Adventure Park built a new sandbox that is 3 / text { m}3 m3, space, m long, 2 / text { m}2 m2, space, m wide, and 1 / text { m}1 m1, space, m high. Sand for the sandbox costs / $4.50 per cubic meter. How much will it cost to completely fill the sandbox with sand?

We are given dimensions of the sand box:

Length = 3m.

Width = 2m and

Height = 1 m.

Volume of the box is = Length * Width * Height.

Plugging values in above formula, we get

Volume = 3 * 2 * 1 = 6 cubic meter.

We are given cost $4.50 per cubic meter.

Therefore, total cost is 6 * 4.5 = $27.

Therefore, it cost will $27 to completely fill the sandbox with sand.
