Answer:
The volume of her cube is .
Step-by-step explanation:
The formula V = s³, where s represents the side length of the cube.
Side length of Marie’s cube is
We need to find the volume of the cube. We can find the volume of the cube using the above formula as follows :
So, the volume of her cube is .
Answer:
The first option
Step-by-step explanation:
See the attached figure to better understand the problem
we know that
in the triangle BCD
y²+5.66²=z²-------> y²=z²-5.66²------> equation 1
in the triangle ABC
y²+5.66²=x²-------> y²=x²-5.66²------> equation 2
equals 1 and 2
z²-5.66²=x²-5.66²--------> z²=x²---------> z=x
if z=x then
angle A=45°
angle D=45°
in the triangle ABD
cos 45=z/(5.66*2)-------> z=11.32*cos 45-----> 11.32*√2/2----> 8
z=8
x=8
y²=z²-5.66²------> 8²-5.66²-----> y²=31.96------> y=5.65
the answer isthe value of x is 8the value of z is 8the value of y=5.65
It would depend but Mikhail's possible age could be 47.
