alisha [4.7K]

Answer:

844368.7 m

Step-by-step explanation:

We are given that a typical sugar cube has an edge length of 1.00 cm.

We have to find the edge length of the box in meters.

Edge length of sugar cube=1 cm =10^{-2}m (1 cm=\frac{1}{100}m)

Volume of a sugar cube=side\times side\time side=(10^{-2})^3=10^{-6}m^3

1 mole of sugar=6.02\times 10^{23}units

Volume of 1 unit=10^{-6} m^3

Volume of 6.02\times 10^{23} units=6.02\times10^{23}\times 10^{-6}=6.02\times 10^{17} m^3

Volume of box=1 mole of sugar=6.02\times 10^{17} m^3

Edge length of box=\sqrt[3]{6.02\times 10^{17}}=844368.7 m
