Question

An object has the dimensions below: Width 2.5 cm Length: 2.0 m Depth: 2.0 cm
What is the area?

Answer 1

For this case, what we must do is suppose that the object is a rectangular prism.

We have then that the surface area of the object is given by:

`A = 2wl + 2wd + 2ld`

Where,

w: width of the rectangular prism

l: length of the rectangular prism

d: depth of the rectangular prism

Substituting values we have:

`A = 2 (2.5) (2.0) +2 (2.5) (2.0) +2 (2.0) (2.0)`

`A = 28cm ^ 2`

Answer:

The object area is:

`A = 28cm ^ 2`

Note: for the problem to make physical sense, we assume that the length is 2 centimeters.
