<span>Call x the distance traveled V = x / t = 89.5 = x / t => x = 89.5t Rest time in hours = 22min * 1 h / 60 min = 11/30 h Total time spent on the trip = t + 11/30 => Average speed = 77.8 = x / (t + 11/30)=> x = 77.8 (t + 11/30) => 89.5t = 77.8 (t + 11/30) => 89.5t = 77.8t + 77.8 * 11/30 => 89.5 – 77.8t = 28.527 => 11.7 t = 28.527 => t = 28.527 / 11.7 => t = 2.44 h => t + 11/30 = 2.81 h => x = 89.5t = 89.5 * 2.44 = 218.3 km Answers: a) 2.81 h; b) 218.3 h </span>

Find the volume of the square pyramid below.
miv72 [106K]

Hello!

\bf ANSWER

The volume of the square pyramid is approximately \boxed{ \bf 19.19~km^3}

____________________________________________________________

\bf EXPLANATION

V = a^{2}\frac{h}{3}

First, we must find the area of the square base.

A = l * w

A = 3.5 * 3.5

A = 12.25 km^2

The area of the base is 12.25 km^2. Now, multiply the base area by the perpendicular height. Then divide by 3.

V = (12.25 * 4.7) / 3

V = 19.1916666667

V ≈ 19.19 km^3
