Question

Need to find surface area

Answer 1

Find the area for each shape.

For the triangle face you would do 4 times 6 divided by 2. Then times it by 2 because there are two triangle faces.

For the rectangle face do 5 times 12, then times 3 because there are 3 triangle faces.

Finally add both numbers together to get the surface area.

Answer 2

You have to break it down into their individual shapes
1st there are two triangles
To find the area for one of them
1/2bh. Or 1/2(4)(6()=12
Multiply the 12 by 2
The area for both triangles are 24
Although there are three triangles, you have to realize that only two of them have the same area
The base is 6*12=72 and there is only one of them
The two side rectangles are
5*12=60 multiply by 2 since there are 2
120

Add all of the areas together
24+72+120=216
Surface area 216 u^2
