Find the surface area of the regular pyramid shown in the accompanying diagram. If necessary, express your answer in simplest radical form.

The area of the pyramid is 360 unit²

Step-by-step explanation:

Given

Base Edge, a = 10

Height, h = 12

Required

Determine the surface area

The surface area of a regular pyramid is calculated as thus;

Substitute values for a and h

Evaluate all squares

Take positive square root of 169

Hence, the area of the pyramid is 360 unit²

7.25

step-by-step explanation:

we know that 7 equals to 7.0. we also know that 1/4=0.25. so we can add the two together and we get 7.25
