Make 'a' the subject of the formulae

V=1/3arsquareh

To make 'a' the subject of the formula, we need to isolate 'a' on one side of the equation.

Given: V = (1/3)ar²h

First, multiply both sides of the equation by 3 to remove the fraction:
3V = ar²h

Next, divide both sides of the equation by r²h to isolate 'a':
a = (3V)/(r²h)

Therefore, 'a' is the subject of the formula.
