Question

a volume of cuboid is 14400cm^3 and it's height is 15cm. the cross-section of the cuboid is a rectangle having its side in the ratio 5:3. find the perimeter of the cross-section​

Answer 1

Answer:

(244√14)/3

Step-by-step explanation:

volume of cuboid = l × b × h = 14400 { given

ratio of length and breadth = 5:3

a/c to q.,

5x × 3x × 15 = 14400

solving it,

x = (2√14)/3

hence,

perimeter of cuboid = 4 × (l + b + h) = 4×(10√14/3+6√14/3+45/3)

= 244√14/3
