Chapter 12: Q27. (page 479)

Find the weight to the nearest kilogram, of the cement block shown. Cement weighs 1700 kg/m³?

Short Answer

Expert verified

The weight of cement block is $19 kg$ .

Step by step solution

Step 1. Given information.

A figure provided in the question,

Step 2. Determine the weight.

Firstly, find the volume of the first brick,

$\begin{matrix} v = 40 \times 20 \times 20 \\ = 16000 {cm}^{3} [multiply] \end{matrix}$

And the volume of upper,

$\begin{matrix} v = 12 \times 10 \times 20 \\ = 2400 [simplify] \end{matrix}$

Then the volume of actual block is,

$\begin{matrix} v = 16000 - 2 (2400) \\ = 11200 {cm}^{3} [multiplyandsubtract] \end{matrix}$

Thus, the weight of the block is,

$\begin{matrix} w = \frac{11200}{1000000} (1700) \\ = 19 kg[simplify] \end{matrix}$
