Question

give me the answer for this question​

Answer 1

Answer:

Here, all we have to do is to find the lateral surface area and then add the area of top part of box.

Step-by-step explanation:

given, l= 2.5m, b= 2m and h=1m

LSA of cuboid= 2(l+b)*h + l*b

= 2(2.5+2)*1+2.5*2

=2(4.5)+5

=9+5

=14 m²

Thanks for asking please mark me as brainliest!!

Answer 2

Answer:

Step-by-step explanation:

Box=cuboid

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

Side of a cuboid=lb

Therefore,

Surface area Mohit painted=2(lb+bh+hl)-lb

2(2.5×2+2×1+1×2.5)-2.5×2

=19-5

=14m^2
