To find the surface area you will need to find the area of all 5 surfaces (faces) on the prism. On a triangular prism there are 2 triangular faces and 3 rectangular faces. All 3 rectangular faces are the same and the 2 triangular faces are also the same.
To find the area of the triangular faces, you will use the formula for finding the area of a triangle:
A = 1/2bh
1/2 x 10 x 8.7
A = 43.5 in^2
To find the area of the rectangular faces, you will use the formula for finding the area of a rectangle:
A = bh
10 x 3
A = 30 in ^2
30 + 30 + 30 + 43.5 + 43.5 = 177
The minimum amount of wrapping paper needed for the gift is 177 square inches.
Answer:
so what's the question? i'm a bit confused..
Step-by-step explanation:
We can solve by figuring the area of the rectangle then add it to the area of the semicircle.
Area of the rectangle: length · width = 6 · 10 = 60 ft²
Area of the semicircle: (πd²)/8 = (3.14 · 6²)/8 = (3.14 · 36)/8 = 14.13 ft²
Total area of the figure: 60 + 14.13 = 74.13 ft² ≈ 74 ft²
Step-by-step explanation:
$450×15%= D (downpayment)
$450-D= B (balance)
B÷18= MB (monthly balance)
MB ×12%= I (interest)
MB+I= MI (monthly installment)
(MI×18)+D= Total Paid

Catch is...YOU have to find it! (:
2.2=4
2.7=14
5-4+14-5=1+14-5=15-5=10
Good Luck!
