Question

What is the total surface area of a right rectangular prism with the base of 2 cm by 3 cm and a heightof 6 cm

Answer 1

72

Explanation:

We can use the equation A=2(wl+hl+hw) to calculate surface area. All we have to do is substitute the known values.

A=2(3(2)+6(2)+6(3)

Now, simplify.

A=2(6+12+18)

A=2(36)

A=72

The total surface area is 72.

Hope this helps!
