Answer 1

Step-by-step explanation:

queation is saying that

The LENGTH BREADTH AND HEIGHT OF A CUBOID ARE

15 CM, 10CM, 20CM ..

WE HAVE TO FIND ITS TOTAL SURFACE AREA

YOUR SOLUTION MATE

given length =15cm

given breadth =10cm

given height=20cm

as we weknow

TOTAL SURFACE AREA OF CUBIC

=2(LB+BH+HL)UNITS

2(15*10+10*20+20*15)CM

2(150+200+300)CM

2(650)CM

1300 CM square

now we come to know that total surface area is 1300cm

hope it helps to u

Answer 2

Step-by-step explanation:

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

= 2 ( 20 × 15 + 15 × 10 + 10 × 20 )

= 2 ( 300 + 150 + 200 )

= 2 ( 650 )

= 1300 ans.
