Question

***HELP NEEDED! WILL GIVE MEDAL!***

Massie bought a glass figure as a souvenir at a museum gift shop. The area of the rectangular base of the pyramid is twelve square centimeters. Its height is 7 centimeters. What is the volume of the pyramid?

twenty-eight cubic centimetres
eighty-four cubic centimeters
four hundred twenty cubic centimeters
one thousand, eight cubic centimeters

Answer 1

Here's the formula

1/2 × Perimeter × [Side Length]
+ [Base Area]

Answer 2

solve by the formula.....

Volume of a pyramid = 1/3 * area of base * height ....

Answer 3

here area of base is 12 and height is 7.... put the values in the formula... and solve....

Answer 4

\[V= \frac{ 1 }{ 3}\]

Answer 5

@Tuff_Lady002 clear.....

Answer 6

\[V=\frac{ 1 }{ 3 }⋅12⋅7=28 cm3\]

Answer 7

I have another one:

Which of these formulas could not be used to calculate the volume of this square-based pyramid?

square-based pyramid

volume equals one-third times base area times height
volume equals one-third times length times width times height
volume equals one-third times side squared times height
volume equals one-third times pi times radius squared times height
