The faces of a cube is a squar
square area=side^2
given
side area=squae area=64

64=side^2
sqrt both sides
8=side

volume =lenght times width times height
in a cube, lenght =widht =height=side=8
in this case they all equal 8

volume=8 times 8 times 8
volume=512 cubic centimeters

The face of one side of a cube is a square shape. The formula for the area of a square
A=s² where s=side length
plug in the data we know
64cm²=s²
√64cm²=s
8cm=s

The side length on the cube is 8cm

The formula for the volume of a cube is

V=s³ where s=side length
plug in the data that we know
V=8³
V=512cm³

3. A mysterious metal medallion has a mass of 3,088 grams. Water is poured into a graduated glass container with a 10-by-10 cm s

Gekata [30.6K]

Step-by-step explanation:

Volume of displaced water = (10cm)(10cm)(1.6cm)

= 160 cm^3

density = mass/vol of displaced water

= 3088 grams/160 cm^3

= 19.3 g/cm^3

P.S. This is most likely a pure gold medallion.

Find the difference.<br><br> 6rs – (-2rs)

lilavasa [31]

There is no difference, 6rs-(-2rs) if you get rid of the parenthesis you are left with 6rs- -2rs and two negatives make a positive therefore the answer will become 8rs... I hope this helps :)
