Find the surface area of the following composite figure.

Question

Find the surface area of the following composite figure. Consider the surface area as anything that light touches. Use 3.14 as pi. Do not round anything until your final answer. Then, round to

the nearest whole number. This number is your next code.

Hint: When you cover your eyes with your hands, your eyes can no longer see light but neither do the palms of your hands.

Answer 1

There are lots of parts here, but if we look at them one at a time, it won't be so overwhelming.

Back side of the square prism: (15)(30) = 450

Top side: (15)(30)-π(7)² = 450-π(7)²

2 Square sides: (15)(15)(2) = 450

2 Triangle sides: 1/2(20)(15)(2) = 300

Rectangle piece: (25)(30) = 750

Circle top: π(7)²

Cylinder side: π(14)(16) = 224π

Total: 450+450-π(7)²+450+300+750+π(7)²+224π = 2400+224(3.14) = 3103.36 ft²
