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

Answer»

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.
