Question

Find the cost of digging a cuboidal pit 8m long 6m broad and 3m deep at the rate of rupees 30 per msquare

Answer 1

Vol= 8*6*3=144m³
1m³= rs 30
Therefor, 144m³= 30*144=4320

Answer 2

Answer:

• Length = 8m
• Breadth = 6m
• height = 3m

$\\ \large{ \underline{ \boxed{ \sf { \pink{volume = l \times b \times h}}}}} \\ \\ \\ \implies \sf \: 8 \times 63 \\ \\ \implies \sf \: 144 \: m.$

Cost of digging pit at the rate of Rs 30 per m³

$\\ \sf \implies \: 144 \times 30 \\ \\ \\ \implies \sf \: rs.4320$
