A metallic sheet is of rectangular shape with dimensions 48 m x 36 m. From each of its corners, a square is cut off so as to make an open box. If the length of the square is 8 m, the volume of the box (in m3) is:
Answer: Option
Explanation:
Clearly, l = (48 - 16)m = 32 m,
b = (36 -16)m = 20 m,
h = 8 m.
Volume of the box = (32 x 20 x 8) m3 = 5120 m3.

By we consider the ratio of volume to the curved surface area why not curved surface area to volume to find radius? Please, anyone, tell me.

Hi, since the length of the square is mentioned, can't we use it directly to calculate volume for the box (cube) in this case. 8^3 = 512?

Here we cut in corners four sides but not in the whole side. So that why we subtract (8+8) from original breadth and length.

Here the box we are talking about is open so why we are not deducting area of upper lid from the volume?

If we have 36 Meter scale and if we deduct 8 Meter from left and 8 meter from right we get 22 Meter.

Here 8 is height of square but not of box height. Then how come rectangle box height will b 8?

No this is not a cube, this is a rectangular solid so the formula is l*b*h.

Why can't we find the remaining area and multiply it by the height?
