Answer 1

hiii!!!

here's ur answer...

A. given length of the cuboid = 20m

breadth of the cuboid = 10m

height of the cuboid = 7m

TSA of the cuboid = 2 ( lb + bh + lh )

= 2 [ ( 20 × 10 ) + ( 10 × 7 ) + ( 20 × 7 ) ]

= 2 ( 200 + 70 + 140 )

= 2 × 410

= 820m²

B. given length of the cuboid = 16cm

breadth of the cuboid = 16cm

height of the cuboid = 20cm

TSA of the cuboid = 2 ( lb + bh + lh )

= 2 [ ( 16 × 16 ) + ( 16 × 20 ) + ( 16 × 20 ) ]

= 2 ( 256 + 320 + 320 )

= 2 × 896

= 1792cm²

hope this helps u..!!
