Answer:
580m^3 / 580000litre , 380m^2
Step-by-step explanation: volume=l*b*h area (in this case)= lb + 2h(l+b)
where h=2.9m (in 1st case) and h= 3m in 2nd
l=20
b=10
volume = 10*20*2.9
= 580m^3 / 580*1000= 580000litre
area = 20*10+2*3(10+20)
= 380m^2 of vinyl
vinyl : A vinyl sheet floor is completely impermeable to water.
