Answer:
125.254..
Step-by-step explanation:
The triangles are 8 inches squared each, since it gives the length and width.
Since there are two triangles, it is 16.
The bottom is 4 by 8, which is 32, the back rectangle is 4 x 8 also, which is 32.
So we now have 32 + 32 + 16.
= 64 + 16
= 80
There is that last slant rectangle, which is harder.
We need to use pythagorean theorum to find that slant length first.\
4 ^ 2 + 4 ^2 = x ^2.
16 + 16 = 32.
32's squared root is something like 5.65685424949, but we will use 5.66.
Multiply that by 8 to get 45.254........
Add 80 + 45.254 = 125.254...
Round if the question tells you to, but this is an approximation due to decimals.
