what is the surface area of 16ft on the bottom 8ft on the right and 5ft on the left???????????????

To find the surface area of a three-dimensional object, we need information about all of its sides. However, you have only provided the lengths of three sides. Without the height or any information on the top side, we cannot determine the surface area accurately.

If you are referring to a rectangular prism or a cuboid, then we need the height or the length of the fourth side to calculate the surface area. Please provide the missing information, and I will be happy to help you calculate the surface area.

I don't understand. A rectangle only has 2 measurements -- length and width.

btw the object is a rectangle

so there numbers r on the bottom and the left bottom is 5ft right bottom is 8ft and middle bottom is 16 ft
