Question

What is the surface area

Answer 1

SA = 554 inches squared

Explanation:

Blue rectangular prism:

3 x 3 = 9

3 x 11 = 33

9 + 9 + 33 + 33 + 33 + 33 = 150

Orange rectangular prism:

6 x 8 = 48

6 x 11 = 66

8 x 11 = 88

48 + 48 + 66 + 66 + 88 + 88 = 404

Surface Area:

150 + 404 = 554

Answer 2

544in sq.

Explanation:

Bigger Rectangle:

[SA]=2(lw+wh+lh)

2(8•11+6•+11•6)

2(88+48+66)

2(202)

[SA]=404

Smaller Rectangle:

[SA]=2(lw+wh+lh)

2(11•3+3•3+3•11)

2(33+9+33)

2(72)

[SA]150

Add both sums together

404+150=554
