Question

find the total surface area of the cuboid with l=4m,b=3m and h=1.5m

Answer 1

Heya !

Here's your answer !!

_____________________________

GIVEN THAT :

In a Cuboid ,

Length ( l ) = 4 m

Breadth ( b ) = 3m

Height ( h ) = 1.5 m

_____________________________

TO FIND :

Total Surface Area of the Cubiod ( T.S.A. )

___________________________

SOLUTION :


T.S.A. of a Cuboid =

2 ( lb + bh + hl ) sq. unit

=> 2 ( 4 × 3 + 3 × 1.5 + 1.5 × 4 ) m²

=> 2 ( 12 + 4.5 + 6 ) m²

=> ( 2 × 22.5 ) m²

=> 45 m² ANS

Answer 2

hey mate !!

here is your answer !!

Answer

45m2

solution

in the questions we find out the total surface area of the cuboid.

In the questions given dimensions of cuboid.

length (l ) = 4m

breadth (b )= 3m

height (h) = 1.5m

here using formula ,

Total surface area of cuboid equal to (TSA) = 2 (lb + bh + hl ) sq units

( TSA) = 2 (lb + bh + hl ) sq units

2 ( 4× 3 + 3×1.5+1.5×4)m2.

2 ( 12 + 4•5+6•0)m2.

2 ( 18 + 4•5)m2.

2(22.5)m2.

45m2.

therefore the total surface area of the cuboid is equal to 45m2.
