Question

A rectangular box has height ℎ cm. Its length is 7 times the height and breadth is 2 cm less than the length. What is the volume of the box?

Answer 1

Answer:

How To Find:

To find the volume of the box, we will use,

Volume = Height × Length × Breadth

Solution:

Using the formula,

⇒ Volume = Height × Length × Breadth

Substitute the values,

⇒ Volume = (h) × (7h) × (7h - 2)

Remove the brackets,

⇒ Volume = h × 7h × 7h - 2

Take variable and numbers seperately,

⇒ Volume = (h × 7h × 7h) - 2

Multiply and solve,

⇒ Volume = 49h - 2 cm³

Answer 2

Step-by-step explanation:

height of the box - h cm

therefore, length of the box - 7h

therefore breadth of the box - 7h - 2c

volume of box - lbh

substituting values

(7h) (7h-2) (h)

(49h sq - 14h) (h)

49 h cube - 14 h sq
