# Solved Problem 08 | Rectangular Parallelepiped

**Problem 8**

An electric refrigerator is built in a form of rectangular parallelepiped. The inside dimensions are 3 ft. by 2.6 ft. by 1.8 ft. A freezing unit (1.1 ft. by 0.8 ft. by 0.7 ft.) subtracts from the storage room of the box. Find the capacity of the refrigerator.

**Solution 8**

Capacity of the refrigerator

$V = 3(2.6)(1.8) - 1.1(0.8)(0.7)$

$V = 3(2.6)(1.8) - 1.1(0.8)(0.7)$

$V = 13.424 \, \text{ ft}^3$ *answer*
