Question

I need help on numbers 1 2 and 3?

Answer 1

Below

Explanation:

To calculate the volume of a pyramid, volume= (area of the base) times height divided by 3
SO say my area of base is A and my height is H then `v=(AH)/3`

Question 1:
Volume = `(15*15*35)/3=2625m^3`

Question 2:
Volume = `(28*21*25)/3=4900(cm)^3`

Question 3:
Volume = `(45*28*50)/(3*2)=10500(yd)^3`
Since the area of the base is a triangle, i also have to divide it by 2
