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» 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 ∴ Thus, the volume of the rectangular box 49h - 2 cm3. |
