Question

find the volume and total surface area of a cuboid whose length is 0.10 m breadth 50 mm class 9th question​

Answer 1

Step-by-step explanation:

Length =15cm

breadth =10cm,

height =8cm

We know that

Volume of a cuboid = Length×Breadth×Height=15×10×8=1200cm

3

Here

Total surface area of a cuboid = 2(l×b+b×h+h×l)=2(15×10+10×8+8×15)

By further calculation

=2(150+80+120)

By further calculation 2×350=700cm^2

Answer 2

Length =15cm

breadth =10cm,

height =8cm

We know that

Volume of a cuboid  = Length×Breadth×Height=15×10×8=1200cm3 

Here

Total surface area of a cuboid = 2(l×b+b×h+h×l)=2(15×10+10×8+8×15)

By further calculation

=2(150+80+120)

By further calculation  2×350=700cm2
