Answer:
h = 2,67 units of length
Step-by-step explanation:
Volume of a cone is
V(c) = 1/3*π*r²
Where π*r² is area of the base
we know V(c) = 40 cubit units, and area of the base 15 square units, then
V(c) = Area of the base * h (height of the cone )
V(c) = 15 * h
h = V(c) / 15 ⇒ h = 40 / 15 ⇒ h = 2,67 units of length
