To calculate the surface area of a triangular prism, we need to find the area of each face and add them together.
The triangular faces have a base of 17m and a height of 15m.
Area of one triangular face = 1/2 (base x height) = 1/2 (17m x 15m) = 127.5m^2
Since there are two triangular faces, their combined area is:
2 x 127.5m^2 = 255m^2
The rectangular faces have a length of 17m and a width of 11m or 16m, depending on which face we're considering.
Area of one rectangular face = length x width
Area of the rectangular face with length 17m and width 11m = 17m x 11m = 187m^2
Area of the rectangular face with length 17m and width 16m = 17m x 16m = 272m^2
Since there are two rectangular faces, their combined area is:
2 x (187m^2 + 272m^2) = 918m^2
Now, we can simply add up the areas of all the faces:
255m^2 + 918m^2 = 1173m^2
Therefore, the surface area of the triangular prism is 1173 square meters.

The length of a rectangular foam packing block is 9 inches. The width is 3 1/4 inches, and the height is 2/3 of an inch. what is the volume of the foam block.
To find the volume of the foam block, we need to use the formula:
Volume = Length x Width x Height
We are given the following dimensions:
Length = 9 inches
Width = 3 1/4 inches
Height = 2/3 inches
First, we need to convert 3 1/4 inches to a mixed number or improper fraction so that we can use it in the calculation:
3 1/4 = 13/4
Now, we can substitute the given values into the volume formula:
Volume = 9 inches x 13/4 inches x 2/3 inches
Simplifying the above equation, we get:
Volume = (9 x 13 x 2) / (4 x 3) cubic inches
Volume = 78/2 cubic inches
Volume = 39 cubic inches
Therefore, the volume of the foam block is 39 cubic inches.

First, we need to identify the dimensions of the rectangular prism using the given net. From the net, we can see that the base of the rectangular prism has dimensions of 4cm x 3cm, and the height of the rectangular prism is 2cm.
Therefore, the surface area of the right rectangular prism can be calculated as follows:
Surface area = 2lw + 2lh + 2wh
Where l, w, and h represent the length, width, and height of the rectangular prism, respectively.
Substituting the values we know, we get:
Surface area = 2(4cm x 3cm) + 2(4cm x 2cm) + 2(3cm x 2cm)
Surface area = 24cm^2 + 16cm^2 + 12cm^2
Surface area = 52cm^2
Therefore, the surface area of the prism is 52 square centimeters.
Hence, the answer is 52 cm units^2.
Therefore, the surface area of the right rectangular prism can be calculated as follows:
Surface area = 2lw + 2lh + 2wh
Where l, w, and h represent the length, width, and height of the rectangular prism, respectively.
Substituting the values we know, we get:
Surface area = 2(4cm x 3cm) + 2(4cm x 2cm) + 2(3cm x 2cm)
Surface area = 24cm^2 + 16cm^2 + 12cm^2
Surface area = 52cm^2
Therefore, the surface area of the prism is 52 square centimeters.
Hence, the answer is 52 cm units^2.
