Question

Find the surface area of the square pyramid shown below.units 2 Base 4 Height 3

Answer 1

To solve;

we will use the formula;

`A=a^2+2a\sqrt[]{(a^2)/(4)+h^2}`

where a is the base and h is the height

From the diagram, a = 4 and h=3

substituting into the formula;

`A=4^2+2(4)\sqrt[]{(4^2)/(4)+3^2}`

`A=16+8\sqrt[]{4+9}`

A= 16 + 8√13

A= 16 + 28.8444

A=44.844 units²
