A block of wood in the shape of a cuboid has length = 2.5 m,
breadth = 1.5 m and height = 2 m. How many cubical blocks,
each of edge 50 cm can be cut from it?
Answers
Answer:
Volume of a cuboid with length L=2.5m, breadth B=1.5m and height H=2m
⇒lbh=2.5×1.5×2=7.5 sq .metre
=7.5×100 cm×100 cm ×100cm
Volume of a cube of length =50×50×50 cubic centimetre
=125×1000 cubic centimetre
=1.25×10
5
cubic centimetre .
No. of blocks cut from the cuboid =
1.25×10
5
7.5×10
6
=60

Answer:
Volume of a cuboid with length
L=2.5m,
breadth B=1.5m
height H=2m
⇒LBH=2.5×1.5×2=7.5 sq .metre
convert into cm
=7.5×100 cm×100 cm ×100cm
Volume of a cube of length =50×50×50 cubic cm
=125×1000 cubic centimetre
=1.25×10 to the power 5 cubic cm
No. of blocks cut from the cuboid =
= 7.5 x 10 to the power 6 / 1.25 x 10 to the power 5
= 60 cubic cm.......
