What is the surface area of the figure 20ft , 12ft , 8ft, 15ft , 8ft , 8ft ?
To find the surface area of this figure, we need to add up the areas of all the individual faces.
There are 6 faces in total:
Face 1: 20ft x 12ft = 240 square feet
Face 2: 20ft x 8ft = 160 square feet
Face 3: 12ft x 8ft = 96 square feet
Face 4: 15ft x 8ft = 120 square feet
Face 5: 15ft x 8ft = 120 square feet
Face 6: 8ft x 8ft = 64 square feet
Adding all these up, we get:
240 + 160 + 96 + 120 + 120 + 64 = 800 square feet
Therefore, the surface area of the figure is 800 square feet.
