\tt Step-by-step~explanation:

To be able to solve this question, we need to know about the Pythagorean theorem: a² + b² = c². A and b represents the two sides that make the right angle, and C represents the hypotenuse, or the longest side, of the triangle.

\tt Step~1:

We know that the hypotenuse is the longest side of the triangle, so that means 9 is c. One side of the triangle is 6, and we have to solve for b. That means 6 is a. We can plug in our values to the formula like this:

\tt a^2+b^2=c^2\\6^2+b+2=9^2\\36+b^2=81

\tt Step~2:

Now that we have our equation down, we know what we have to do next: subtract 81 from 36 to get b².

\tt 81-36=\sqrt{45}

\Large\boxed{\tt Our~final~answer:~b=\sqrt{45} ~(simplified:3\sqrt{5}) }

What is the volume of a square pyramid with base edges of 60 inches and a height of 10 inches?
vichka [17]

Answer:

The volume is 12000 in^3

Step-by-step explanation:

From the question ,

L= 60\:in. and H=10\:in.

The volume of a pyramid is given as

V=\frac{1}{3} \times area\:of\:the\:base \times height

From the question, the base of the pyramid is a square.

Hence base area is given by L^{2}

This implies that the volume of the pyramid is

=\frac{1}{3} \times L^{2}\times H

=\frac{1}{3}\times 60^{2} \times 10

=\frac{36000}{3}

=12000 in^3
