a refrigerator is 3 ft wide, 2.5ft deep,and 6ft high. The walls and other parts other refrigerator take up to 20ft. How much cubic feet are left for food?

V = 3 * 2.5 * 6
V = 45
45  20 = ? 
so if you do 3*2.5=7.5*6=45...you yae 45 from the three numbers you just multiplied and you got 45....now do 25 that is the part of the fridge and do 4520=25 feet3=25 feet cubed!!!

the swimming pool is 12 ft. wide , 25 ft. long , and 6 ft. deep. how many cubic feet are needed to fill the pool
