A right rectangular prism has a volume of 470.40 cm³. The length of the solid is 6.4 cm and the width is 9.8 cm.
Bogdan [553]
V = l * w * h
470.40 = 6.4 * 9.8 * h
Multiply the length and width on the right side of the equation.

470.40 = 62.72 * h
Divide both sides by 62.72
7.5 cm = h

CHECK
V = l * w * h
V = 6.4 * 9.8 * 7.5
V = 470.4 cm^3
