Question

Need help with geometry

Answer 1

48

Explanation:

Formula: a^2*(h/3)

We know a is 6ft, but to find h, the height, we'll need to use Pythagoreon Theorem. The hypothenuse of the triangle is 5 and one of the legs is 3, because you need to divide 6 by 2.

3^2+b^2=5^2

9+b^2=25

b^2=16

b=4

Now plug in a and h into the formula to get 48.

Answer 2

V = 60

Explanation:

The formula for the volume of a square based pyramid is: V = a² × h/3 where a = the edge and h = the height

to solve we just plug it in:

V = 6² × 5/3

V = 36 × 5/3

V = 36/1 ×5/3 (another way of writing the above)

V = 180/3 <-- simplify

V = 60
