Answer:
2) 360 square inches
Step-by-step explanation:
First of all we have to verify that the base triangle is a right triangle
For this we use Pythagoras
h² = l1² + l2²
13² = 12² + 5²
169 = 144 + 25
169 = 169
Equality is fulfilled by what is a right triangle
Now we need to calculate the area of the triangle
a = (12 in * 5 in) / 2
a = 60in² / 2
a = 30in²
Now we have to calculate the 3 areas of the rectangles
a1 = 10in * 13 in
a1 = 130in²
a2 = 10 in * 12 in
a2 = 120in²
a3 = 10 in * 5 in
a3 = 50in²
Now we must add all the calculated areas and the triangle 2 times
a1 + a2 + a3 + 2a =
130in² + 120in² + 50in² + 2 * 30in²
360in²
The surface area of the prism is 360in²

Answer:
64
Step-by-step explanation:
In each supply bag, Mrs. Wilson packed 3 rubber bands and 4 paper clips for her students.
Now, it is given that she had used 48 rubber bands.
Hence, there will be (48/3) =16 supply bags that had been used.
Now, in 16 supply bags, there will be (16×4) =64 paper clips.
Therefore, 64 paper clips that she had used. (Answer)
