Given:
A figure of a rectangular prism with length l, width w and height h.
To find:
The surface area of the rectangular prism.
Solution:
The product of twice of the length l and the width w is:
...(i)
The product of twice of the length l and the height is:
...(ii)
The product of twice of the width w and the height h is:
...(iii)
The surface area of the prism is the sum of (i), (ii) and (iii). So, the expression for the surface area is:
Therefore, the required expression is 
.
Answer:
Communative: 12 x 5= 5 x 12 Associative: (5) + 6 = (8) + 3 Identity: 5 x 1= 5
Step-by-step explanation:
Given:
a.) The scale of the model is 1 in equals 47 ft.
b.) Danielle constructs a scale model of a building with a rectangular base her model is 2 inches in length and 1 inch in width.
To be able to determine the actual area of the base, let's first identify the actual dimensions of the base.
We get,
Let's now solve for the area of the base, since it is a rectangle, we will be using the formula below:
We get,
Therefore, the actual area of the base is 4,418 ft.².
Answer:
congruent, proportional
