Question

find the cost of digging a cuboidal pit 8m long 6m broad and 3m deep at the rate of Rs 30 per
${m}^{2}$
​

Answer 1

Volume of cuboid= length x breath x height

= 8 x 6 x 3

=144m^3

Cost of digging the pit= 144 x Rs 30

= 4320 Rs

Answer 2

$\huge\bold\red{ANSWER}$

TOTAL SURFACE AREA OF CUBOID = 2(lb + bh + lh)

T.S.A = 2[(8×6)+(6×3)+(3×8)]

T.S.A =2(48 + 18 + 24)

T.S.A =2 × 90

T.S.A $= {180m}^{2}$

COST OF DIGGING = 180 × 30

= RUPEES . 5400
