Question

6. The volume of a cuboid is 3240 cm³'. Its length,
breadth and height are in the ratio 8:5:3. Find
the dimensions of the cuboid.​

Answer 1

Answer:

Length = 24 cm

Breadth = 15 cm

Height = 9 cm

Step-by-step explanation:

l:b:h = 8:5:3

Let l = 8x

b = 5x

h = 3x

Volume of cuboid = lbh cu.units

3240 = 8x × 5x × 3x

3240 = 120x³

x³ = 3240/120

x³ = 27

x = 3

Length = 8x = 8 × 3 = 24 cm

Breadth = 5x = 5 × 3 = 15 cm

Height = 3x = 3 × 3 = 9 cm

Hope it helps you:)
