The density of the marble will be "0.18 kg/m³".
According to the question,
Volume of marbles,
- V = 25 cm³
By converting it into m, we get
- 0.25 m³
Mass,
- M = 45 g
By converting it into kg, we get
- 0.045 kg
As we know, the formula:
→
By substituting the values, we get
→
→
Thus the answer above is correct.

Answer:
a) 18 in x 18 in x 18 in
b)
Step-by-step explanation:
a) Let's call 's' the side of the square base and 'h' the height of the solid.
The surface area is given by the equation:
The volume of the solid is given by the equation:
From the volume equation, we have that:
Then, using this value of h in the surface area equation, we have:
To find the side length that gives the minimum surface area, we can find where the derivative of S in relation to s is zero:
The height of the solid is:
b) The minimum surface area is:
