Answer:
3.6
Step-by-step explanation:
Pythagorean theorem:
a^2 + b^2 = c^2
(6 km)^2 + b^2 = (7 km)^2
36 + b^2 = 49
b^2 = 13
b = sqrt(13)
b = 3.6
Answer: 3.6 km
You just need to plug those expressions inside the formula: it doesn't matter if they're expressions involving a variable instead of plain numbers: the formula becomes

If you want, you can simplify it by expanding the square and then multiply the two parenthesis:

Answer:
60,000
Step-by-step explanation:
Jane-2000
Peter-ratio of 5=25000
Marta-ratio of 7=35000
25000+35000
60000
To get the volume, you need the area of the sides of the square.
The total surface area is 96, with 6 sides. To get the surface area of just one side, divide 96 by 6, which gets you 16. The surface area of a single square is 16. To get one side of the square, divide that by 4 because there are 4 sides.
Now, multiply 16 by 4 to get the volume.
The volume is 64 cubed milllimeters.
