Question

Find the surface area of the square pyramid shown below.
​

Answer 1

Answer: 40 units²

Step-by-step explanation:

To find the surface area of the triangular sides, multiply the length by the height.

4*3=12

Now, you need to multiply 1/2 by 12 since this is a triangle.

12 * 1/2=6

6 is the surface area for all the triangular sides so since there are 4 of those sides, we get 24.

The square bottom side is 4 by 4 since squares have 4 equal sides. WE need to multiply the length by the width.

4*4=16

Add all the sides and we get 40²

Answer 2

Answer:

40

Step-by-step explanation:

Base= 4 times 4 = 16

Lateral face= 4 times 3 times 0.5 = 6

There are 4 sides so times it by 4 = 24

Add 16 = 40
