Question

A pit 25 metres long and 3.5 M wide is dug to a certain depth if the volume of earth taken out of it is 14 what is the depth of the pit

Answer 1

Answer:

GIVEN:

Length of a pit (l) = 5 m

Breadth of a pit (b) = 3.5 m

Volume of Earth taken out = 14 m³

Let the depth of a pit = h m

Volume of cuboidal pit = Volume of Earth taken out

l × b × h = 14 m³

5 × 3.5 × h = 14 m³

h = 14 /(5×3.5)

h = 140/( 5×35)

h = 20/ (5 × 5) = 20/25= ⅘ = 0.8 m

h = 0.8 m

h = 0.8 × 100 = 80 cm  [ 1m = 100 cm]

Hence, the depth of the pit is = 0.8 m or 80 cm.
