Question

Find the Surface Area.

Answer 1

17.6ft^2

Explanation:

triangular prism surface area = bh + (s1 + s2 + s3)H

where bh=base*height (of triangle)

s1=side 1(of triangle)

s2=side 2(triangle)

s3=side 3(triangle)

h=height(AKA length of rectangle)

so height of the triangles 2 and base=1

2+(1+2+2.2)3

2+(5.2)3

2+15.6=17.6

17.6ft^2

Answer 2

8.6ft squared

Explanation:

Let's start with the front.

1 x 2 / 2= 1ft squared 82 (for both sides)= 2ft squared

3 x 2.2 / 2= 3.3 ft squared *2 (for both sides)= 6.6 ft squared

6.6 + 2= 8.6ft squared
