The open topped box will have dimensions of length = 40- 2(8) = 24 cm, width = 40- 2(8) = 24 cm & height 8 cm
Now what are the formulas for surface area (as it is open topped, do you need to do indside and out?) and volume?
can anyone help me solve this problem, please?
A piece of cardboard measures 40 cm by 40 cm. An open-topped box is to be constructed by removing a square with side length of 8 cm from each corner and folding up the edges.Find the surface area of the box. Find the volume of the box.
so, "subtract the top i.e. LW from the result" as you have mentioned above. do i have to do this then 2(LW-LH-WH)
Also, i got the volume - > volume= (l*w*h)=24*24*8=4608
Thanks again for your reply and your time. can you look at it and reply please.
