Exercise 22 Page 46

Practice makes perfect

a We need to isolate the variable h in the given formula.

V=1/3Bh

LHS * 3=RHS* 3

3V=Bh

.LHS /B.=.RHS /B.

3V/B=h

Rearrange equation

h=3V/B

b In the diagram, the values of V and B are provided. We can use our rewritten formula to find the height h.

h=3V/B

V= 216, B= 36

h=3 * 216/36

Multiply

h=648/36

Calculate quotient

h=18

The height of the pyramid is 18 centimeters.
