fast pleaese given a pyramid l = w = 9.0 mm and v = 324.0 cubic mm , find h in mm.

(enter a numerical answer)

Answers

The answer to your question is height = 12 mm

Step-by-step explanation:

Data

l = w = 9 mm

V = 324 mm³

h = ?

Formula

V = \frac{Ab x h}{3}

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 = \frac{3(324)}{81}

Simplification

                       h = \frac{972}{81}

Result

                       h = 12 mm                    

the answer is 12 mm

Step-by-step explanation:

its 12 because the teacher said it was.            

h = 12mm

Step-by-step explanation:

The volume of a pyramid is given as :

V = \frac{1}{3} lwh

Therefore:

324 = \frac{1}{3} lwh

324 x 3 = 9 x 9 x h

Therefore:

h = 972/81

h = 12mm
