Question

5 1/4 m^3 of copper sheet weigh 1563kg.what will be the weight of 3 1/2 m^3 of sheet​

Answer 1

Answer:

The required weight of 3.5 m³ of sheet is 1042 kg

Step-by-step explanation:

Given,

• 5.25 m³ of copper sheet weigh 1563 kg.

We are to find the weight of 3.5 m³ of sheet.

We will be using the unitary method to solve the given problem.

Unitary method : The unitary method is a technique for solving a problem by first finding the value of a single unit, and then finding the necessary value by multiplying the single unit value.

Weight of 5.25  m³ of copper sheet = 1563 kg.

So, the weight of 1 m³ of copper sheet will be   $\dfrac{1563}{5.25}~\textup{kg}.$

∴ The weight of 3.5 m³ of copper sheet is given by

$\dfrac{1563}{5.25}\times3.5=1042~\textup{kg}.$

Thus,

The required weight of 3.5 m³ of sheet is 1042 kg.
