Question

water fowsfrom a time with the rectangular base measuring 80 CM by 70 cm into a tank with a square base of 60 CM if the water in the first rank is 45 CM deep house di will it be in the second tank

Answer 1

$volume \: of \: first \: tank = volume \: of \: second \: tank \\ 80 \times 70 \times 45 = 60 \times 60 \times h \\ h = \frac{80 \times 70 \times 45}{60 \times 60} \\ h = \frac{56 \times 45}{6 \times 6} = 14 \times 5 = 70cm$
