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
