9. Find the volume of the triangular pyramid. (2pts)-10 mI9 m16 m
Makovka662 [10]

Answer:

240 m³

Explanation:

The volume of a pyramid is equal to:

V=\frac{1}{3}\times B\times H

Where B is the area of the base and H is the height of the pyramid.

Then, the base of the pyramid is a triangle, so the area of a triangle is equal to:

B=\frac{b\times h}{2}

Where b is the base of the triangle and h is the height of the triangle. So, replacing b by 16 m and h by 9 m, we get:

B=\frac{16\times9}{2}=\frac{144}{2}=72m^2

Finally, replacing B by 72 m² and H by 10 m, we get that the volume of the pyramid is equal to:

V=\frac{1}{3}\times72\times10=\frac{1}{3}\times720=240m^3

Therefore, the volume is 240 m³

This problem sounds so ridiculous lol

All joking aside, first let's look at the multiples of 1000.

1000, 2000, 3000, 4000, 5000, 6000

That makes 6.  Complete the following equation, and you have your answer.

6 / 6296 = ?

0.000953 if you round.
