Question

a) Find the volume
Volume, the T.S.A , L.SA
cuboid which is 8m. x6 m x 3.5cm​

Answer 1

, we find volume of cuboid equal to 168m3 and we find curved surface of cuboid 98 m2 . and also the total surface area of cuboid equal to 194m2.

Step-by-step explanation:

hey mate !!

HERE IS YOUR ANSWER !!

according to questions ,

in the question given the length of the cuboid 8 metre and breadth of the cuboid 6 metres and also height of the cuboid mentioned in the questions 3.5metre.

here we find ,

v of cuboid = ?

CSA of cuboid = ?

TSA of cuboid = ?

like ,

length = 8 m

breadth = 6 m

height = 3.5 m

then , we find volume of cuboid

here ,

v of cuboid = l × b × H

using formula,

v = l × b × H

v = 8 × 6 × 2.5

v = 168 m^3

again , we find c.s.a of cuboid

CSA of cuboid = 2 ( l + b ) h

using formula ,

2 ( l + b ) h

2 ( 8 + 6 ) 3.5 m2

2 ( 14 ) 3.5 m2

28 × 3.5 m2

{98m}^{2}98m

2

now , we find TSA of the cuboid .

TSA of cuboid = 2 ( lb + bh + hl )

using formula

2 ( lb + bh + hl )

2 ( 8 × 6 + 6 × 3.5 + 3.5 × 8 )

2 ( 48 + 21 + 28)m2

2 ( 97) m2

= 194 m2

therefore, we find volume of cuboid equal to 168m3 and we find curved surface of cuboid 98 m2 . and also the total surface area of cuboid equal to 194m2.
