if this was a carboard box and you 'unwrapped' it you would have 3 rectangles, and 2 triangles.

If you work out the area of each face you have the total area

how am i supposed to know the area of each face

mouth4war · Answer

? sorry if that sounded rude i meant it as a genuine question

mrnood · Answer

you have all the dimansions in the drawing

you need to know how to work out the area of a rectangle, and the area of a triangle.

These must be part of your study - so you should know them - or refer to your text
