A box has four sides. you have to find out each perimeter and you have to add .

Example: A rectangular shape box having length L ,width W and height H .Find its perimeter.

Perimeter=4(L+W+H)

you mean a rectangular prism? or a rectangle?

For a rectangle, perimeter is 2(sideA)+2(sideB) and area is sideA x sideB

For a rectangular prism, there are diferent terms used

the area becomes volume and the formula is: the Length of the box x the Hight x the Width

Let x, y, z be the dimensions

Perimeter = 4(x+y+z) because there are 4 edges in each direction.

Area = 2(xy + xz + yz) because there is a pair of opposite squares for each combination of 2 dimensions

Volume=xyz.

i'm assuming you mean square/rectangle and not cube, right?

perimeter, add the lengths of the sides

area, length x width

if its a square or a rectangle, you can find the area by multiplying the length, the width and the height.
