It helps to draw diagrams when working through problems like this.
Given a rectangular prism (the suitcase), drawing a diagonal through its side will give you two right triangles. You can use the Pythagorean Theorem (a² + b² = c², where c is the hypotenuse of a right triangle) to find the length of the unknown side. The hypotenuse of the triangle is the diagonal since it is the longest side, and it is opposite the right angle.
a² + b² = c²
a² + 24² = 26²
a² + 576 = 676
a² = 100
a = 10 in
Remember that this is only the side length of the triangle. To find the amount of material needed to cover one side of the suitcase, we need its area. We can find the area using the formula for area of a rectangle: A = bh.
A = bh
A = 10*24
A = 240 in²

Answer:
5.60 pounds each
Step-by-step explanation:
This is the dry mixture problem.
Let x = the number of pounds of the first type of candy
Therefore, number of pounds of second type of candy = 10-x
Value of first candy + value of second candy = value of mixture
Value of any candy = cost per pound of candy * weight of candy
Thus:
4x + 6(10 - x) = 5.60(10)
4x + 60 - 6x = 56
-2x + 60 = 56
-2x = -4
x = -4/-2
x = 2
Therefore, the number of pounds of first type of candy = 2 pounds
The number of pounds of second type of candy = 10 - 2 = 8 pounds
Check
$4(2) + $6(8) =
8 + 48 = $5.60(10)
$56 = $56
