Chapter 12.1, Problem 26WE

To determine

To find: the weight of the water.

Answer to Problem 26WE

The weight of water is $0.56$ metric ton.

Explanation of Solution

Given information:

A figure provided in the question,

  

Calculation: to find the weight, first find the volume of drinking trough,

  $\begin{array}{l}v=\frac{1}{2}\left(40\right)\left(100+40\right)\left(200\right)\\ v=560000{\text{cm}}^3\text{ [add and multiply]}\\ v=0.56{\text{m}}^3\text{ [simplify]}\end{array}$

Thus, the weight of the water is $0.56$ metric ton.
