The edge of a cube made of zinc is 4cm. Find the mass of a cube if the mass of 1cm ^ 3 zinc is 7 g.

Rib length – 4 cm.

1 cm ^ 3 – is 7 g.

Let’s determine the mass of this cube. We write down the resulting solution.

First, we find the volume of the given cube. In order to find the volume, we multiply the length by the width and by the height. All sides of a cube are equal. Hence, we get the following solution.

V = a ^ 3.

V = (4 cm) ^ 3 = 64 cm ^ 3.

This means that the volume of the cube is 64 cm ^ 3.

It is further known that 1 cm ^ 3 is equal to 7 grams. Find the mass of the cube if the volume is 64 cm ^ 3.

64 * 7 = 448 g.

This means that the mass of the entire cube is 448 grams.

Answer: the mass of the cube is 448 g.
