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?

• math -

V = 3 * 2.5 * 6
V = 45

45 - 20 = ?

• math -

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 45-20=25 feet3=25 feet cubed!!!
