A rectangular prism as 6 sides, 2 of each dimensions.
So this has 2 sides that are 5 x 5
2 sides that are 10 x 5
and 2 sides that are 10 x 5
Find the area of each, multiply by 2 then add them all together:
5 x 5 = 25
10 x 5 = 50
10 x 5 = 50
(25 + 50 + 50) x 2 = 250 m²
➷ Surface area is simply the total of the area of each surface:
area of square = length x width
area of square = 5 x 5
area of square = 25
As there would be 2 squares (one at the front, one at the back), we need 2 times this value
25 x 2 = 50
area of rectangle = length x width
area of rectangle = 10 x 5
area of rectangle = 50
As there would be 4 rectangles, we need 4 times this value:
50 x 4 = 200
Surface area = total area of rectangles + total area of squares
Surface area = 200 + 50
Surface area = 250 m^2
