Answer:
7m
Step-by-step explanation:
The volume of a pyramid is given by the following formula: 1/3bh. Where 'b' represents the area of the base and 'h' the height of the pyramid.
The area of the base is: b = (3m)(4m) = 12m^2
Now, we know that the volume is 28m^3, then:
28m^3 = (1/3)(12m^2)(h)
Solving for 'h':
h = 7m
