Answer:
y = -3 and y = -3
or y = -3 with a multiplicity of 2
Step-by-step explanation:
If you want to factor this, heres what you do:
Then factor:
The value of y:
y + 3 = 0 and y + 3 = 0
y = -3 and y = -3
or y = -3 with a multiplicity of 2
The surface area of the triangular prism is 686.6 cm².
Step-by-step explanation:
Step 1:
The volume of a triangular prism can be determined by multiplying its area of the triangular base with the length of the prism.
The base triangle has a base length of 10 cm and assume it has a height of h m.
The volume of the prism
The height of the triangle is 8.66 cm.
Step 2:
The surface area of the triangle is obtained by adding all the areas of the shapes in the prism. There are 2 triangles and 3 rectangles in a triangular prism.
The triangles have a base length of 10 cm and a height of 8.66 cm. A triangles area is half the product of its base length and height.
The rectangles all have a length of 20 cm and a width of 10 cm. The area of a rectangle is the product of its length and width.
The area of the 2 triangles
The area of the 3 rectangle
Step 3:
The surface area of the triangular prism
The surface area of the prism is 686.6 cm².
