Answer:

h = 80

Step-by-step explanation:

Remark

The general Volume formula for a pyramid is V = 1/3 * B * h

Givens

base edge = 3 m

V = 240 m^2

Solution

V = 1/3 * B * h

B = s^2

B = base edge^2

B = 3^2

B = 9

240 = 1/3  * 9 * h             multiply by 3

240 * 3 = 9 h                   Divide by 9

80  = h
