Question

) A wooden block 6m×15cm×40cm is cut into planks of measurements 2m×2.5cm×4cm.

Find the number of planks to be cut off from it.​

Answer 1

Answer:

Number of Planks to be cut off = 180

Step-by-step explanation:

Dimensions of Wooden Block :

l = 6 m = 600 cm

b = 15 cm

h = 40 cm

Dimensions of a Plank :

l = 2 m = 200 cm

b = 2.5 cm

h = 4 cm

Number of Planks to be cut off from the Wooden Block = Volume of Wooden Block

____________________

Volume of a Plank

= l × b × h

______

l × b × h

= 600 × 15 × 40

__________

200 × 2.5 × 4

= 180

So, number of Planks to be cut off from the Wooden Block = 180
