change in volume = surface area * delta h delta volume/volume = 45 * 9.5 * 10^-4 volume = 3 liters = 3*10^-3 m*3 so delta volume = 3 *10^-7 *45 * 9.5 = 1282*10^-7 m^3 surface area = .135*.13 = 1.755*10^-2 so 1.282*10^-4 = 1.755 *10^-2 delta h delta h = .73 * 10^-2 meters or ....

4.8 litres = 4.8*1000 cm³=4800 cm³ Volume = width*length*height, therefore height=volume/(width*length) =4800 cm³/(15 cm * 20 cm) =16 cm Total side surface area = sum of area of 4 vertical faces = 2(height*length+height*width) = 2(16cm*15cm+16cm*20cm) = 2(240+...

recall surface area and volume of cube is given by SA = 6*s^2 V = s^3 where s = length of a side the volume becomes 1/8 of original so V' = 8 cubic units. thus, 8 = s^3 s = cuberoot(8) s = 2 (new length) the surface area of a cube of this length is SA = 6*(2^2) SA = 24 sq ...

I'm assuming length is depth. A rectangular solid has 6 sides, so the total area will simply be 6 times the area of one side. The area of one side is the area of square which is w*h. The volume of a rectangular solid is l*w*h. From Google, "The lateral area is the surface area...

No figure is shown. As I understand your description of the problem, the minimum area and volume would be obtained as the height approaches zero. The volume would then be zero. The surface area (including base) would then approach 2 pi r^2.

I would say it is the mean, averaged over the area, which is what you get by dividing lake volume by surface area. "Anonymous" is not an approved Jiskha teacher.
