Question

Help please?

A rectangular prism has length 12 inches, width 4 inches, and height 3 inches. What is the surface area of the prism?

Answer 1

surface area = 2 x length x width x height.

Answer 2

lol. i missed something

SA = (2 x length + 2 x width) x height

Answer 3

basically, surface area is always perimeter x height. If it's enclosed, multiply it by 2 again

Answer 4

To put it more simply, the total surface area which you are trying to find, is the area of each face of the object added all together

Answer 5

so draw the prism quickly and label the given measurements, then find the area of each face(there should be six in this case) and then add them together.

Answer 6

tip: notice that two are corresponding faces are the same

Answer 7

Volume of Rectangular Prism:

V = L*W*H



Surface Area of Rectangular Prism:

SA = 2*(L*W + W*H + L*H)
