Answer:
10 cm
Step-by-step explanation:
Since, the volume of a cuboid is,
V = l × w × h,
Where,
l = length,
w = width,
h = height,
∵ The shape of the aquarium must be cuboid,
We have, l = 20 cm, w = 12 cm, V = 2400 cm³,
By substituting the values,
2400 = 20 × 12 × h
2400 = 240h
Hence, the height of the water in Nemo's aquarium would be 10 cm.
I'm sorry I don't have answer but.
it's not C!
C option is correct.
t = 8 +- √ 1− 4 d
d=−16t^2 +4t
t= (1+ √ 1− 4 d) / 8
t = (1 − √ 1 − 4 d ) / 8
y = 2
6y-5=7
+5 +5
6y=12
/6 /6
y=2
