To calculate the surface area of the triangular prism, we need to find the area of each face individually and then add them all up.
The two triangular faces have a base of 16cm and a height of 6cm.
Area of one triangular face = 0.5 * base * height
Area of one triangular face = 0.5 * 16cm * 6cm
Area of one triangular face = 48cm²
Since there are two triangular faces, the total area of both faces = 2 * 48cm² = 96cm²
Now, for the three rectangular faces:
- Two faces have a length of 20cm and a height of 6cm
- One face has a length of 16cm and a height of 6cm
Area of one rectangular face = length * height
Area of one rectangular face = 20cm * 6cm = 120cm²
Area of one rectangular face = 16cm * 6cm = 96cm²
Total area of all rectangular faces = 2 * 120cm² + 96cm² = 336cm²
Total area of all faces = area of two triangles + area of three rectangles
Total area = 96cm² + 336cm² = 432cm²
Therefore, Chocolate place would need 432cm² of red foil for packaging one chocolate bar.
Chocolate place makes a candy bar in a shape of a triangular prism. The person is represented by the NAV net given for packaging. The top in the bottom are covered in gold foil. The faces are covered in red file how many centimeters of red file is needed for the one chocolate bar. Height 6cm sides 10cm base 16cm length 20 cm
