Question

A closed storage water tank in the shape of a cube is 7 meters long the tank was painted on all the interior faces calculate the area painted in square meters

Answer 1

The area painted will be the total surface area of all the interior faces of the cube.

Since the cube has 6 faces, each having an area of 7m x 7m = 49 square meters. Therefore, the total area painted on all the interior faces of the cube will be:
6 faces x 49 square meters/face = 294 square meters

So, the area painted on all the interior faces of the cube is 294 square meters.
