Find the total area of the solid figure with the length, 3 width 5, and height 6

To find the area of a rectangle multiply its height by its width. For a square you only need to find the length of one of the sides (as each side is the same length) and then multiply this by itself to find the area.

Good Luck

A = w x l x h

A = 3 x 5 x 6

A = 90
