Question

Find the volume of a cube whose volume is three times the volume of a cuboid
of dimensions 20cm x 15cm x 10cm.​

Answer 1

Answer:

mark me as brainlist

Step-by-step explanation:

Volume of a cuboid of length l, breadth b and height h =l×b×h

So, the volume of the cuboid with length =15cm, breadth =10cm and height =8cm=15×10×8=1200cm

3

Total surface area of a cuboid of length l, breadth b and height h =2(l×b+b×h+l×h)

So, the total surface area of the cuboid with length =15cm, breadth =10cm and height =8cm=2(15×10+10×8+15×8)=2(150+80+120)=700cm

Answer 2

Answer:

Volume of cuboid = ( l × b × h )

( 20 × 15 × 10 )

= 3000cm³

Volume of cube = 3000 × 3 = 9000cm³
