Worth 25 points and i’ll give brainlist What is the total surface area
of the square pyramid below?

A 100 cm2
B 200 cm2
C 280 cm2
D 380 cm2

D) 380cm^2

Step-by-step explanation:

In order to find the surface area, find the area of each side then add them all.

The formula for this would be:

base area + 4(side area)

To find the area of the base multiply 10 by 10

10 x 10 = 100

To find the area off the triangle sides multiply the width (10) by the height (14) and divide by 2

(14 x 10) ÷ 2 = 70

Because there are four sides, multiply 70 by 4 then add the product to 100

70 x 4 + 100 = 380cm^2
