Question

If the volume of this cube (15 cm and 5 cm) is 525 cm3,then the length of the missing side is what cm?

Answer 1

Its 7


Just multiply 15 and 5 which gives you 75. Take 525 and divide it by 75 and you get 7. You can check your answer by multiplying (what you got for your answer) x 5, then that result is multiplied by 15 and you should get 525.
