Question

TSA of the cuboid with... length=60, breadth=40,height=50
pls ans this question​

Answer 1

Answer:

14,800 sq. units

Step-by-step explanation:

We are given,

l= 60

b= 40

h=50

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

= 2(60x40+40x50+50x60)

= 2(2400+2000+3000)

= 2x7400

= 14,800 sq. units

Hope it helps......

Pls mark as brainliest!!!

Answer 2

Total surface area of a cuboid =

2 [ ( l × b ) + ( l× h ) + ( b× h )]

= 2 [( 60 x 40 ) + ( 60 x 50 ) + ( 40 x 50 )]

= 2 [( 2400 ) + ( 3000 ) + ( 2000 )]

= 2 x 2400 + 3000 + 2000

= 2 x 7400

= 14,800 unit²
