I don't know how to set up a diagram for this, but I could write an expression. 20*4= x
sorry, but I hope this helps. I not even sure my expression is correct.
1/3 times 6/8
1/3 times 3/4
So, the answer is 3/12
Simplify: 1/4
The sum of the 2 angles will add up to 180°
Surface area = area of 3 rectangles + 2 triangles
= 3*(3*7) + 2 * ( 1/2 * 3 * 2.6)
= 63 + 2* 3.9
= 70.8 in^2
