<em>V = 120 in^3</em>

<u><em>Here is why:</em></u>

The volume formula for a pyramid is:

V=\frac{1}{3}Bh

The B stands for the area of the base, which in this case is a right triangle. We will find the area of the right triangle first, then plug it into the equation.

The area formula for a triangle is:

A=\frac{1}{2}bh

Plug in the numbers.

A=\frac{1}{2}*9*10

A = 45

Now we have found the area of B, we can plug it into the volume formula for the pyramid.

V=\frac{1}{3}*45*8

V = 120 in^3

the slide at the playground has a height of 6 feet.The base of the slide measured on the ground is 8 feet.what is the length of
NemiM [27]
The formula for finding the length is
{a}^{2}  +  {b}^{2} = {c}^{2}
All we have to do is plug in the numbers.

{6}^{2}  +  {8}^{2}  =  {c}^{2}
36 + 64 = 100

Since 100 =
{c}^{2}
we have to find the square root.

\sqrt{100}  = 10

The length of the slide is 10 feet.
