Answer:
Height = 6 units
Step-by-step explanation:
Recall that the volume of a pyramid is defined as:
Volume = 1/3 Base x Height
Then, in our case we have:
140 = 1/3 (70) x Height
we multiply by 3 both sides to eliminate the fraction on the right:
420 = 70 Height
divide by 70 to isolate the Height completely:
420 / 70 = Height
Therefore, the height is:
Height = 6 units
