AB + BC = AC

or, 3x-16 + 4x-8 = 60

or, 7x = 60 + 24

or, 7x = 84

A square pyramid has a base length of 4 inches. The height of each triangular face is 12 inches. What is the surface area of the

Wittaler [7]

Answer:

The surface area of the given pyramid is 112 $inches^{2}$ .

Step-by-step explanation:

Base length of the pyramid = 4 inches

Area of the base = $length^{2}$

= $4^{2}$

= 16

Area of its base = 16 $inches^{2}$

Area of one of its triangular surface = $\frac{1}{2}$ x base x height

= $\frac{1}{2}$ x 4 x 12

= 2 x 12

= 24 $inches^{2}$

Area of all its four triangular surfaces = 4 x 24

= 96 $inches^{2}$

surface area of the pyramid = sum of areas of all its surfaces

= 16 + 96

= 112 $inches^{2}$

The surface area of the given pyramid is 112 $inches^{2}$ .
