Can anyone help me find the surface area of this shape?

1 answer:

8 0

To find the surface area of a cuboid you have to find the areas of all the faces and then add them all up together.
2*2=4
4+4=8 (adding this because there's 2 of these same faces)
9*2=18
18*4=72 (because there's 4 of these same faces)

8+72=80

So the answer is 80cm

A right rectangular prism has a length of 2 1/2 feet, a width of 3 feet,and a height of 1 1/2 feet. Unit cubes with side lengths

Illusion [34]

The statement "unit cubes with side lengths of 1/2 foot are added to fill the prism with no space remaining" is useless information so you can disregard that. All you need to know to calculate the volume is the length, width, and height.

Volume = length x width x height
Volume = (5/2) x 3 x 11/2
Volume = 15/2 x 11/2
Volume = 165/4
Volume = 41.25 ft cubed
