Consider this:If a cube has side length d, then its volume is d3 and its surface area is 6d2.If I cut the cube into 8 smaller cubes by bisecting each edge, then the new side length is d/2, the sum of the volume is 8 * ((d/2)3) = d3, and the surface area is 8 * (6(d/2)2) = 12d2.Therefore, even though the volume stayed constant, the sum of the surface area increased when I cut a larger cube into small cubes. The increase in surface area will be larger and larger as the cube is cut into smaller and smaller pieces. Therefore a sugar cube always has less surface area than an equal mass of sugar crystals.Granulated sugar has more surface area than a sugar cube.

A planet with a greater mass does not necessarily have greater surface area than one with less mass. The planet could be made of denser material and have a smaller surface area. Mass doesn't always mean volume.

You must be with K12 if you are it is The surface area of A is greater than the surface area of B.

Yes this is true.

The surface area is 600 centimeters.

The sugar crystals because there is a greater amount of surface area readily exposed for chemical reaction.

In a chemical reaction it is likely that a single cube will react more quickly than an equal mass of sugar crystals. This is due to the fact that the surface area of a single cube is much smaller than the total surface area of the sugar crystals. The larger surface area of the sugar crystals increases the amount of time it takes for the reactants to reach the surface and begin the reaction.The following points explain why a single cube would react more quickly than an equal mass of sugar crystals: A single cube has a much smaller surface area than an equal mass of sugar crystals. The smaller surface area of the single cube allows the reactants to reach the surface and begin the reaction more quickly. The larger surface area of the sugar crystals increases the amount of time it takes for the reactants to reach the surface and begin the reaction.In conclusion it is likely that a single cube will react more quickly than an equal mass of sugar crystals due to the larger surface area of the sugar crystals.

The speed at which something dissolves is a function of its surface area. A spoon of sugar and a sugar cube may have the same mass, but the tiny crystals in the spoon of sugar have a cumulative surface area much larger than that of the cube.

it is all about surface area. if you were to stir it the sugar crystals would have water on all sides, but when sitting in the bottom of a cup the water has to dissolve the crystals on the outside, and then it would keep going.

Pipe cleaners have more surface area, and therefore, more places for crystals to grow, than sticks.

the greater the surface area the greater the pull

The granulated sugar would react more quickly, as it has more surface area to react in.

Caster sugar will dissolve quicker because because of a greater surface area.

A sugar cube would dissolve faster than a single sugar crystal of the same mass because it has a greater surface area (sugar cubes aren't solid; they're lots of little sugar crystals stuck together). The difference in speed between a sugar cube and normal (small) sugar crystals ought to be negligible with the crystals having perhaps a slight edge.

When the granules dimension of a material is lowered the surface area is increased and the reaction rate is higher.

The free flowing sugar crystals have more free surface area and shorter diffusion paths than a tightly packed cube. Thus chemistry and dissolution both occur faster. VERY fine sugar can explode if suspended in air.
