The answer to your question is height = 12 mm

Step-by-step explanation:

Data

l = w = 9 mm

V = 324 mm³

h = ?

Formula

V =

Solve for h

3V = Ab h

3V / Ab = h or h = 3V / Ab

Find the area of the base

Ab = l x w

= 9 x 9

= 81 mm²

Substitution

h =

Simplification

h =

Result

h = 12 mm

h = 12mm

Step-by-step explanation:

The volume of a pyramid is given as :

V = lwh

Therefore:

324 = lwh

324 x 3 = 9 x 9 x h

Therefore:

h = 972/81

h = 12mm
