Geometry- surface area and volume of toblerone box
The measurements from my box are W-28cm L-17.4cm H2.4cm. I have to find the surface area of the box, as well as the volume.For the volume, I have the formula 1/2 base*height*width, so would that be 1/2 * 17.4 * 2.8 * 2.4, or do i find the area of the triangle, and then multiply by the height? For the surface area, would i find the area of the rectangle( 17.4 * 2.8) and then multiply by three for the three rectangles, and then find the area of the end triangle, and multiply by 2?
Im just a little confused.Thanks!

Re: Geometry- surface area and volume of toblerone box
Hi;
Welcome.
Looking at Bob's drawing below I have recomputed the answers. I never had toblerone because I do not eat chocolate.
For the volume you use base * height * width.
You will get 584.64 cm^3
Which are you now calling base, height and width?
In mathematics, you don't understand things. You just get used to them.
Probability is the most important concept in modern science, especially as nobody has the slightest notion what it means.
90% of mathematicians do not understand 90% of currently published mathematics.

Re: Geometry- surface area and volume of toblerone box
Are you sure you are talking about the same object?
These measurements don't seems right for a Toblerone box.
I've put a picture below with lettered points. Is this the box you are asking about?
