I I need to find the surface area of this triangular prism.

scoundrel [369]

Answer: P=5.2 h=3 B=2

Step-by-step explanation:

To find P, you add everything except for 3 because P starts for perimeter of the bases and 3 is the height of the prism. So P would equal 5.2. Then to get h, it’s just 3 because that’s the height of the prism. Now for B, you just multiply 1x2 because that’s the area of the base and you only need one. If you’re looking for total surface area, the answer is 19.6 becasue the formula is Pxh+2B meaning perimeter x height plus 2 x B. But for lateral, the answer is 15.6 because it’s just Pxh (perimeter x height) hope this helps lol sorry it’s so long.

Four square pieces of corkboard are lined up to make a rectangle. The area of the entire corkboard is

Pavel [41]

9514 1404 393

Answer:

a) attached

b) 100 square inches, 1/4 of the total

c) square root of area

d) multiply by 4

Step-by-step explanation:

a) A diagram is attached

b) If the total area consists of 4 squares of the same size, then the area of one square will be 1/4 of the total area. 1/4 of 400 square inches is 100 square inches, the area of one square.

c) The area of a square is the square of the side length. You find the side length by finding the square root of the area. √(100 in²) = 10 in, the side length of each square.

d) The rectangle is 4 squares laid side by side, so its length is 4 times the side length of one square: 4×10 in = 40 in.
