Calculate the height of a rectangular prism with length 10.4cm breath 14.5cm and volume 1342.12cm3?

This is simple arithmetic.

v = h x w x l

1342.12 = h x 10.4 x 14.5 The rule is you can do any valid operation on both sides of an equation and it will still be equal. Divide by 10.4 and then by 14.5.

8.9 = h
