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..!!
