The floor area of the office is 21m2 and the height is 3m. Calculate the volume of the office.

The cabinet has the shape of a rectangular parallelepiped.

For this shape, all six of its faces are rectangles. Opposite faces are parallel to each other and the same.

We write down the formula for determining the volume of a rectangular parallelepiped:

V = a * b * c = S * c;

V is the volume of the parallelepiped;

a and b – the length and width of the base of the figure;

S is the base area;

с – figure height.

Let’s substitute the values of the floor area and cabinet height into the formula and find its volume:

V = 21 m2 * 3 m = 63 m3.

Answer: the volume of the office is 63 m3.
