Question

the dimensions of a cuboidal box are 6m×400m×1.5m. find the cost of painting its entire outer surface at the rate of ₹22 per cm^2

Answer 1

Answer: Rs 1323960000

Step-by-step explanation:

L = 6m

B = 400m

H = 1.5 m

Surface area = total surface area

= 2( LB + BH + LH)

= 2 ( 6 × 400 + 400 × 1.5 + 6 × 1.5)

= 2 ( 3009 )

= 6018 m^2 or 60180000 cm^2

Cost of painting per cm^2 = rs 22

So price = 22 × 60180000

= rs 1323960000

Hope it helps!

Answer 2

Answer:

Rs. 1716

Step-by-step explanation:

TSA of cuboid= 2(lb+bh+lh) sq.units

= 2(6*4+6*1.5*4*1.5)

= 78 metre square

Cost of painting = 22*78=rs.1716
