Question

A cubical container of dimensions 2 m×2 m×2 m is to be made using a sheet of metal.
How much will the container cost if the metal sheet costs $24 per m2

Answer 1

SOLUTION

GIVEN

A cubical container of dimensions 2 m × 2 m × 2 m is to be made using a sheet of metal.

TO DETERMINE

The cost if the metal sheet costs $ 24 per m²

FORMULA TO BE IMPLEMENTED

Total surface area of a cube of side a unit is

= 6a² sq.unit

EVALUATION

Here it is given that the cubical container of dimensions 2 m × 2 m × 2 m is to be made using a sheet of metal

So side of the cube = 2 m

So total surface area of the cube

$\sf{ = 6 {a}^{2} \: \: {m}^{2} }$

$\sf{ = 6 \times {2}^{2} \: \: {m}^{2} }$

$\sf{ = 6 \times 4 \: \: {m}^{2} }$

$\sf{ = 2 4 \: \: {m}^{2} }$

Now the metal sheet costs $ 24 per m²

So the required total cost

= $ ( 24 × 24 )

= $ 576
