Question

the length and breath of cuboid in ratio is 5:3. If its height is 7 cm and volume is 2625cm,find its height

Answer 1

Answer:

25

Step-by-step explanation:

Let the ratio be 5x : 3x.

Volume of cuboid = l × b × h.

Given, Volume = 2625 cm³ and height (h) = 7 cm.

=> 5x × 3x × 7 = 2625

=> 105x² = 2625

=> x² = 2625/105

=> x² = 25

=> x = 5

Length = 5×5 cm = 25 cm
