Question

Find the total surface are of a cuboid with dimensions 6cm , 5cm , and 3cm . also, find the cost of painting its lateral surface at ₹5 per cm square ? ​

Answer 1

Step-by-step explanation:

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

tsa = 2 ( 30 + 15 + 18)

tsa = 2 ( 63 )

tsa = 126 cm

lsa = 2 ( l + b ) h

lsa = 2 ( 6 + 5 ) 3

lsa = 2 * 11 * 3

lsa = 66 cm

COST OF PAINTING = 66 * 5

COST OF PAINTING = $ 660
