You buy a ring box as a birthday gift that is in the shape of a triangular prism. what is the least amount of wrapping paper needed to wrap the box?
(my picture is above.)

We are given triangular prism with height 8cm and three sides as 10 cm, 10.5 cm and 14.5 cm.

Now surface area is given by:

Area of three rectangular faces :

face 1: (l*w) = 8*10.5 = 84 cm²..................(1)

face 2: (l*w) = 8*10 = 80 cm² ....................(2)

face 3: (l*w) = 14.5 * 8 =116 cm² ..................(3)

Now we have two right angled triangles here with base 10 cm and height 10.5 cm.

Area of triangle is given by

plugging base and height,

Area of two triangles = 105 cm²................(4)

Adding the four areas to get the total surface area

Area= 84 +116 +80 + 105 = 385 cm²

Answer : the least amount of wrapping paper needed to wrap the box is 385 square cm.

answer is d-29

step-by-step explanation:

since you didn't include the picture, i can give you the description so you know how to pick the correct answer. the third quartile of a data is always shown in a box plot. in the middle of your graph should be a box. the third quartile is the value that goes with the far right edge of the box.

i can you with this sweetie!
