Question

please give me his answer part e​

Answer 1

Answer:

Volume = l×b×h

= 60×30×20

=36000 cm³

Total Surface area = 2(lb+bh+lh)

= 2(60×30+30×20+60×20)

= 7200 cm²

Pls mark me as brainliest and follow me so that I can answer ur qs kyuki mujhe sapna toh aayega nhi ki aap qs poochhe ho but NOTIFICATION aayega if u follow me and also thank all my answers

Answer 2

(e) ☆ Surface area of a cuboid = 2 × (lb + bh + hl)

Given :

length = 60 cm

breadth = 30 cm

height = 20 cm

(put the values in the formula)...

=> 2 × (60 × 30 + 30 × 20 + 20 × 60 )

=> 2 × (1800 + 600 + 1200)

=> 2 × 3600

=> 72,00 cm^2

hence, the surface area of cuboid = 6800 cm^2

☆ Volume of the cuboid = l × b × h

(again just put the values)...

=> 60 × 30 × 20

=> 1800 × 20

=> 36,000 cm^3

hence, we get the volume of cuboid = 36,000 cm^3

Hope this helped you dear...
