Question

Helen has 48 cubic inches of clay to make a solid right pyramid with a base edge measuring 6 inches.



Which is the slant height of the pyramid if Helen uses all the clay?

3 inches
4 inches
5 inches
6 inches

Answer 1

I surmise the base is square.

Answer 2

It looks like a pyramid ?

Answer 3

im sorry yes its a square

Answer 4

Just put Volume(Pyramid)=48 ans solve for h.
Use the Pythagorean identity, then.

Answer 5

okay

Answer 6

wait could we do it together?

Answer 7

\[V(Pyramid)=\frac{ lwh }{ 3 }\]

Answer 8

so you replace the lwh with 6?

Answer 9

The l and w are the length and width of the base.
Since it's a square, these are equal. Just substitute and work out the value of h (Which you don't have).
