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

Hope This Helps You!

Good Luck (:

Have A Great Day ^-^
