How many cubic yards of material are needed for the foundation of a barn 40 by 80 ft., if the foundation is 2 ft thick and 12 ft high?

OR

An electric refrigerator is built in the 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

Answer 1

long sides are 2x 80x2x1 = 320 ft³

short sides are 2x 40x2x1 = 160

corners are 4x 2x2x1 = 160

total = 640 ft³ or 23.7 yd³

volume = 3x2.6x1.8 - 1.1x0.8x0.7 ft³

you do the math.
