Answer:169.92 cm^2

Explanation:

The base is 7.2 x 7.2 (This equals 51.84)

The area of one triangle is 29.52

There are 4 triangles with the same side lengths so you multiply 29.52 x 4.

This would equal 188.08.

Then you add everything together.

This equals 169.92 cm^2.

Answer:1,000 m^3

The formula for volume is hlw.

One of the side lengths of the cube is 10.

If the height, length, and width are ten, then you multiply them all together.

This would give you 1,000.
