In relation to ∠X, 3 is the adjacent side and 13 is the opposite side.
Given:
Box A has a surface area of 98 in².
Box B is 4 times the size of box A.
To find:
The surface area of box B.
Solution:
Let "a" be the side of box A , then "4a" be the side of box B because box B is 4 times the size of box A.
We know that the areas of similar figures are proportional to the square of their corresponding sides.
Using cross multiplication, we get
Therefore, the surface area of box B is 1568 in².
