Find the surface area #3
2 answers:
hmm so... notice the picture below
a "triangular prism" is just 3 rectangles and 2 triangles stacked up to each other at the edges
thus, just find the area of those 3 rectangles, and the area of the 2 triangles, add them up, and that's the surface area of that triangular prism
notice, you have 2 rectangles of 33x39 and the rectangle on the floor is 33x30, and notice both of your triangles have a base of 30 and a height of 36

You could start by noticing
so you don't have to worry about the decimal point anymore. Then carry out the division as usual.
172*24 = 4128
so we have
4172 = 4128 + 44 = 172*24 + 44
