Question

2. The measures of a box are 40 cm, 30 cm and 20 cm respectively. How much square cm cloth is required to make the cover of the box.​

Answer 1

Answer:

cloth required is equal to the total surface area of the box.

TSA of box = 40 × 30 × 20

=> 24000 sq cm

therefore 24000 sq cm of cloth is required to cover the box

Answer 2

Answer:

$24000 {cm}^{2}$

Step-by-step explanation:

CLOTH REQUIRED = TOTAL SURFACE AREA OF BOX

SINCE MEASURE OF DIMENSIONS IS NOT SAME THIS INDICATES THAT BOX IS CUBOIDAL

SO TSA OF CUBOID= L×B×H

=> 40×30×20

$24000 {cm}^{2}$

CLOTH IS REQUIRED
