Best ResponseYou've already chosen the best response.0Hi. The surface area of a right rectangular prism is: A = 2(wl + hl + hw), where A is area, w is width, h is height, and l is length.

Best ResponseYou've already chosen the best response.0Excellent. Area works the same exact way.

anonymous

Best ResponseYou've already chosen the best response.0Now imagine instead of 'circles' I drew 'inches'. Well, to get the total number of inches, it's the same way you calculated the number of circles I drew.

Best ResponseYou've already chosen the best response.0Sure, no problem. Look at the black box I just drew. The box is 1 inch by 1 inch, making it a square. There are 24 of these squares in my 6 inch by 4 inch area.

Best ResponseYou've already chosen the best response.0This is why it is called 24 inches "squared." I have 24 squares. Are you following?

Best ResponseYou've already chosen the best response.0We have 2 areas with 120 inches squared. That equals 120 inches squared + 120 inches squared.
