You are missing one of the dimensions if you want to determine cubic feet. The square footage of a 3'x6' rectangle would be 18 sq ft. You simply multiply the two dimensions (assuming they are already the same unit of measure.) Lets say the rectangular prism is 3'x6'x3' the cubic feet would then be 90 cubic ft. The formula for cubic feet of a rectangular prism is 2ab+2bc+2ac. In this example the formula looks like this, 2(3x6)+2(6x3)+2(3x3)=90.
A = LxW A = 3x6 A = 18 ft squared.
Multiply the length by the wide. eg a 3cm x 6cm rectangle - 3x6=18sqcm The answer is in square units, - square feet, metres, mm etc

The answer will depend on the measurement units used for 3x6.
616 3x6 inch tiles are needed to cover exactly 77 square feet.

There are about 8 pieces of 3X6 in one square foot (depends on grout lines to some extent). 8 x 15 sq feet would be 120 tiles.
3x6=18 square feet.
9x2 . 2x9 . 18x1 . 1x18 . 3x6 . 6x3 all = 18
