a cuboidal shaped closed water tank measuring 3.5 m in length, 2.5m in breadth and 2 m in height is to be constructed. what is the cost of constructing the water tank if the cost of tin sheet is rs. 120 per m²?

length =3.5m
bredth=2.5m
height=2m
TSA of cuboidal tank=2(lb+bh+hl)
=2(3.5×2.5+2.5×2+2×3.5)
=2(8.75+5+7)
=2×20.75
=41.5m^2
cost of constructing=120×41.5
=rs4980

we need to find total surface area
so
total surface area cuboid is 2(lb+bh+lh)
now, 2(3.5×2.5+2.5×2+2×3.5)
= 2(8.75+5+7)
= 2×20.75
= 41.50 metre square
now,
41.5×120
=4980 rs
if you satisfied then give me brainlist
THANK YOU
