Question

What is the total surface area of the tent in square feet? Assume no material is used on the bottom of the tent.
A. 117
B. 162
C.234
D. 246

Answer 1

There are total 8 surfaces of the tent. See the diagram
We need to calculate the surface area of each part
2 is opposite to 1 and 2=1
similarly
4=3
6=5
8=7

Answer 2

Did you understand this?

Answer 3

So far, yes.

Answer 4

But everytime i calculate the surface area of each part and add it, it's always an answer that isn't part of the options

Answer 5

Let's find the surface area of 1
tell me what is it?

Answer 6

We'll work step by step and get the right answer

Answer 7

wouldn't i need to know the base area to find it? i only see the height and slant height

Answer 8

Find base and then calculate
Hint Use Pythagoras

Answer 9

I got 6 for the base, is that right?

Answer 10

Yeah:D proceed now:)

Answer 11

I got 86 in total

Answer 12

That's not the answer, let's do step by step and then we'll get the correct answer. What's the area of 1?

Answer 13

that would be 45

Answer 14

if we're doing it as a rectangle

Answer 15

Height=4, base you calculated as 6
so Area of 1
\[Area_1=\frac12 \times 4 \times 6=12\]
