The length of the room is 8m, width is 7/8 length, and height is 2.6m. Find the volume of the room.

We find the width of the room, provided that it is 7/8 of its length, equal to 8 m.
In order to find the part of an integer value, you must divide it by the denominator of the fraction and multiply by its numerator.

8: 8 * 7 = 7 m.

The volume of a rectangular parallelepiped, in this case a room, is calculated by the formula:
V = a * b * c.

Substitute the known values:

V = 8 * 7 * 2.6 = 145.6 m³.
