Question

the base of cubiod is 63 sq cm and it's volume is 504 cu.cm Find its height​

Answer 1

Answer:

Step-by-step explanation:

Volume of the cuboid = Length ( h ) X Breadth ( b ) X Height ( h ) = 440 cm3

Therefore : l X b X h = 440 cm3

Area of base = l X b = 88 cm2

Therefore : 88 X h = 440 cm3

=> h = (440/88) = 5 cm

Answer: Height= 5 cm .

Answer 2

Step-by-step explanation:

Given that l=20cm, b=12cm, h=9cm

∴T.S.A=2(lb+bh+lh)

=2[(20×12)+(12×9)+(20×9)]

=2(240+108+180)

=2×528

∴T.S.A=1056cm
