Question

FIND THE COST OF DIGGING A CUBOIDAL PIT 8 METRE LONG 6 METRE BROAD AND 3 METRE WIDE AT THE RATE OF RUPEES 30 PER METRE SQUARE​

Answer 1

here your answer ✍✍✍✍

length of cuboidal pit l=8m

Breadth b=6m height h=3m

∴ Volume of pit V=l×b×h

=8×6×3

=143m3

∴ cost of digging a cuboidal 1m3 is Rs.30

Cost of digging a cuboidal pit for 144m3....?....

=144×30

=Rs4320

Answer 2

${\huge {\underline {{\mathtt{\orange{4320}}}}}}$

Step-by-step explanation:

Length of a cuboidal pit = 8 m,

breadth = 6 m and depth = 3 m

Volume/Intemal space of the pit

$= 8m \times 6m \times 3m = 144 m3$

Cost of digging 1 m³ space is Rs. 30

Cost of digging 144 m³ space

$= Rs \: 144 \times 30 = Rs \: 4320$
