Question

a cardboard box is 14 cm long,8cm wide and 6cm high.how much cardboard in cm² will be required to make a closed box



pls give the correct solution ​

Answer 1

Answer:

ANSWER is 72 cube ! it is the right answer

Answer 2

Direct Answer:

Total surface area = 488 cm²

Given:

A carboard box of the given dimensions:

★ Length = 14 cm

★ Breadth = 8 cm

★ Height = 6 cm

To Find:

The total area of carboard which will be required to make a closed box.

Solution:

In the question, we are given with the dimensions of a carboard box and we are asked to find the total area of cardboard which will be needed to manufacture a closed box with the given dimensions. Here, we will have to implement the total surface area formula of a cuboid to find our answer.

Formula to be used:

$\sf{\implies\:TSA\:of\:a\:cuboid=2(lh+bh+lb)}$

✳ Substituting the values we know into the formula,

$\sf{\longrightarrow\:TSA=2[(14\times6)+(8\times6)+(14\times8)]}$

✳ Simplifying the expression further,

$\sf{\longrightarrow\:TSA=2[84+48+112]}$

$\sf{\longrightarrow\:TSA=2\times244}$

$\bf{\longrightarrow\:TSA=488\:cm^2}$

Therefore a total area of 488 cm² cardboard is required to make a box of the given dimensions.

Knowledge Bytes:

★ TSA refers to the total surface area which means the total area of the material used to make a three dimensional figure. It is usually expressed in meter square/ centimeter square.

★ TSA of a cuboid = 2 (lh + bh + lb)

★ LSA of a cuboid = 2 (lh + bh)

★ Volume of a cuboid = lbh
