Hey!!

anonymous · Answer

The surface area is the sum of the area of all the sides.

anonymous · Answer

yup

redbubbles · Answer

so add up all the numbers or multiply?

anonymous · Answer

You need to find the area of each side.

mathmale · Answer

to find the area of each side, you're going to need formulas for 1) the area of a rectangle and 2) the area of a triangle.

mathmale · Answer

Once you have the individual areas, you'll ADD them up.

find perimeter of a triangle = sum of 3 sides
then multiply h= 34
