So far, you've told us the area of the top and bottom of the box ... 45 cm2.
We can calculate the volume, but first you'll also have to tell us how deep
the box is, i.e. the height.
The volume of the box will be 45 cm3 for every cm of height between the top
and bottom of the box.
15cm in width and 10 cm in length
3,375 cm3 is.
80cm.
Each side of the cube would be 15cm in length.
15 cm is a measure of length and a length has no surface.
15cm in width and 10 cm in length
you cant. volume is 3 dimensional so you need width and height of the volume as well as the length
3,375 cm3 is.
Perimeter = 2 lengths and 2 widths In your case length + width = 25cm If length is 5cm more than width then length = 15cm and width = 10cm
You can consider the beam to be a rectangular block. In other words, simply multiply length x width x height.
80cm.
Each side of the cube would be 15cm in length.
area = length x width = 20 x 15 = 300 sq cm
The volume is 1,767 cm3
