What is the surface area of the prism?

Step-by-step explanation:

122

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.

the answer is 48m^2!
