Answer:
The surface area of the triangular prism is 84 square centimeters.
Step-by-step explanation:
The surface area of a figure is exactly what it means, the area of its outer surface or the added areas of each face that makes the figure.
Nets are a way to find surface area easier because it is an outline of the faces of the 3d figure.
But since we don’t have a net, we will just find the area of each face that forms this right triangular prism:
The two congruent triangular bases:
1/2 x 4 x 3 = 6 cm^2
6 x 2 = 12 cm^2
Lateral bottom rectangular face:
6 x 3 = 18 cm^2
Lateral to the right rectangular face:
5 x 6 = 30 cm^2
Lateral to the left rectangular face:
4 x 6 = 24 cm^2
Add up all the values:
12 + 18 + 30 + 24 = 84
The SA is 84 square centimeters
Answer:
D.
Step-by-step explanation:
Answer:
D. 4 x -2 - 7/8
Step-by-step explanation:
4 x -2 7/8
2 7/8 can be separated into 2 pieces 2 +7/8
4x - (2+7/8)
Distribute the minus sign
4x - 2 -7/8
Since y intercept if one, i automatically know the answer is y = 1/2x + 1. The second one
