Answer:
3375
Step-by-step explanation:
The surface area formula for a cube is:
A = 6 a^2
We know what the area is so plug it into the equation:
1350 = 6 a^2
225 = a^2
a = 15
Now plug a = 15 into the equation for volume of a cube:
V = a^3
V = 15^3
V = 3375
Answer:
B
Step-by-step explanation:
-2 x -0.7 + 3.2 = 3.2
Answer:
Step-by-step explanation:
h^2=x^2+y^2, since this is a square x=y=s so
220^2=2s^2
2s^2=48400
s^2=24200
s=24200^(1/2)m (exact)
s=155.56m (rounded to nearest hundredth of a meter)
One hectare is equal to 10000m^2
A=24200m^2(h/10000m^2)
A=2.42 hectares
