Question

Capacity of the tank is 180 kl. If the length and breadth of the tank respectively 6m and 5m, its depth is ​

Answer 1

Answer:

It is open from the top.

∵ Its surface area = [Lateral surface area] + [Base area]

= [2(l + b)h] + [l × b]

= [2(1.50 + 1.25)0.65 m2] + [1.50 × 1.25 m2]

= [2 × 2.75 × 0.65 m2] + [1.875 m2]

= 3.575 m2 + 1.875 m2 = 5.45 m2

∵ The total surface area of the box = 5.45 m2

∴ Area of the sheet required for making the box = 5.4

Answer 2

Answer:

Required depth is 6 m.

Step-by-step explanation:

Given, capacity of the tank is 180 kl

We know volume of a tank is equal to capacity of the tank.

We know volume of the tank = Length × Breadth × Depth

It is also given that the length and breadth of the tank respectively 6m and 5m.

According to question,

$6 \times 5 \times depth = 180 \\ depth = \frac{180}{6 \times 5} \\ depth = 6$

So, required depth is 6 m.

This is a problem of Volume.

Volume related more information:

Volume is a measure of the three-dimensional space occupied. It is often quantified numerically using SI-derived units (such as the cubic meter and liter) or various imperial or US customary units (such as the gallon, quart, cubic inch). The definition of length (cube) is interrelated with volume. Container volume generally refers to the volume of the container; i.e., the amount of fluid (gas or liquid) that the container would hold, not the amount of space that the container itself displaces.
