How can adding doubles multiply by 2?
Multiplication (of positive integers) can be defined as repeated addition. Thus, 2 x 23, for example, is the same as 23 + 23, while 3 x 20 = 20 + 20 + 20. Thus, adding a number to itself is equivalent to multiplying it by 2.Multiplication (of positive integers) can be defined as repeated addition.

Find the surface area of a triangular prism with height 30 in and a right triangle base with side lengths 15 in and 20 in and hypotenuse length 25 in?
Surface area = 2 x area_triangular_ends + areas_of_3_rectangular_faces Surface area = 2 x (15 x 20)/2 + 30 x 15 + 30 x 20 + 30 x 25 = 15 x 20 + 30 x (15 + 20 + 25) = 300 + 30 x 60 = 2100 in2
