Explanation:
it depends whether the coat is a light or dark colour. if it is lighly coloured it will not absorb heat from the sun and wont melt the snowman. if it is darkly coloured it will be number 1

it coul keep in the cold and block out the warmth so number 3

Answer:
1) Mass of the grain is 
.
2) 0.08901 kg of sand would have surface area equal the surface area of the cube.
Explanation:
1) Radius of the grain,r = 64.8 µm =
Volume of the sphere =
Volume of the grain of a sand:
Density of a grain of sand = 
Mass of a grain of a sand = M
Mass of the grain is .
2) Surface are of sphere: 
Surface area of a grain:
Length of the cube = a = 0.514 m
Total surface area of cube ,A'= 
let the number grains with area equal to total surface area of cube be x.
Volume of x number of grains :V'
Mass of 
of sandL:
=
0.08901 kg of sand would have surface area equal the surface area of the cube.
