What is the surface area to volume ratio of a 5 cm cube?
joja [24]
Answer: 6/5

Explanation:
Given: 5cm cube
This means each side is 5 cm because a cube has equal sides.

Area of a square is length times width so area of 1 side of a cube:
= 5 x 5
= 25

Surface area is the area of one side of a cube times the number of sides. Now, how many sides does a cube have? 6
= 25 x 6
= 150

Surface area of a 5cm cube = 150

Volume is length times width times height:
= 5 x 5 x 5
= 125

Ratio of surface area to volume:
= 150/125
= 6/5

\frac{8}{6}  = 1.33

   2- landmark on the first map is a triangle with side lengths of 3 mm, 4 mm, and 5 mm.

Side lengths of the landmark on the second map

Divide the length by scale factor:

side lengths of 3 mm:  \frac{3}{1.33} = 2.25 mm

side lengths of 4 mm:  \frac{4}{1.33} = 3.007 mm

side lengths of 5 mm:  \frac{5}{1.33} = 3.75 mm
