Question

Find the volume of the triangular pyramid to the nearest whole number.

A) 679 in3
B) 906 in3
C) 1,359 in3
D) 2,717 in3

Answer 1

The answer is B. the answer as a decimal is 905.67 round to the nearest whole number you will get 906

Answer 2

B) 906 cubic inches.

Explanation:

The volume of a triangular pyramid is defined as

`V=(1)/(3)((1)/(2)b_(1) h_(1) )h_(2)`

Where,

`b_(1)=19in\\h_(1)=13in\\h_(2)=22in`

Replacing all given values in the formula, we have

`V=(1)/(6)(19in)(13in)(22in) \\V=(5,434)/(6)in^(3) \\V \approx 906 in^(3)`

Therefore, the right answer is B.
