Question

A block of marble is in the shape of a rectangular prism 6 The block is 3 feet long 2 feet wide and 18 inches high What is the volume of the block

Answer 1

Volume of a rectangular prism can be found with the equation

v = length × width × height

They are trying to trip you up a little bit here because they give 2 measurements in feet then the last in inches. So for your prism...

18 inches = 1.5 ft

v = l×w×h
v = 3×2×1.5

v = 9 ft^3
