Answer:

The surface area 76.32 in^2

Step-by-step explanation:

To find the surface area of a square pyramid we have to find the area of the base and the area of the sides and add them together.

Area of the base:

Since the base is a square, all we have to do is multiply 3.6 by 3.6.

3.6 * 3.6 = 12.96

The area of the base is 12.96 in^2

Area of the sides:

Since the sides are triangles, to find the area we have to multiply the length by the height and divide by 2.

3.6 * 8.8 = 31.68

31.68/2 = 15.84

The area of one of the sides is 15.84

Surface Area:

To find the surface area we have to add the area of the base and the area of the 4 sides together.

12.96 + 4(15.84)

12.96 + 63.36 = 76.32

The surface area is 76.32 in^2

alexgriva [62]

Answer:

Perry's claim is correct while Karina is incorrect

Step-by-step explanation:

Question is incomplete (See Attachment)

First, we need to determine the area covered by Karina and Perry

For Karina, there are 9 square boxes each of which has an area of 1 unit sq

So:

$Karina = 9 * 1\ unit^2$

$Karina = 9\ unit^2$

For Perry:

There are 18 square boxes, each of which has an area of 1 unit sq.

So:

$Perry = 18 * 1\ unit^2$

$Perry = 18\ unit^2$

Comparing both areas, we can conclude that <em>Perry's claim is correct while Karina is incorrect</em>
