Answer:
2250000 m
Step-by-step explanation:
firstly given the width =30 dm convert it into cm and then into M
it would be = 3m
samely for the height = 12dm
= 120cm
= 1.2 M
now we have to find the length of the cuboid we are given speed we will convert it into m by following l=30/60*100
therefore length=50 km
= 50000
next we will find the volume of water used for cuboid =50000*3*1.2
=180000
now finally we can find the area of the field 8/100=180000
=2250000 m2
hope it helps ya
