Hector covers each face of the pyramid below
1 answer:
The image is missing, so i have attached it.
Answer:
area he will cover with paper = 196 in²
Step-by-step explanation:
From the image, we see that the base of the face= 8 inches while the height is 14 inches.
We know area of triangle is;
A = (1/2) x base x height
Thus;
A = (1/2) x 8 x 14 = 55 in²
This is area of one side face.
Thus area of 3 side faces = 56 x 3 = 168 in²
Thus, total area covered is;
Area of side faces + area of base = 168 + 28 = 196 in²
