Apuzzle contains a triangular piece with a base of 3 in. and a height of 4 in. a manufacturer wants to make 80 puzzles. find the amount of wood used if each puzzle contains 20 triangular pieces.

I believe this question asks for the total amount of area of wood that is needed to make 80 puzzles.

The formula for area of triangle is given as:

A = (1 / 2) b h

where,

b = is the base of the triangle = 3 in

h = height of the triangle = 4 in

So calculating for area of 1 on triangle (A1):

A1 = (1 / 2) (3 in) (4 in)

A1 = (1 / 2) 12 in^2

A1 = 6 in^2

We are given that we are to make 80 puzzles and each puzzle has 20 triangles, therefore the total amount of triangles we need to make is:

n = 80 * 20

n = 1600

Therefore the total area needed (A) is:

A = A1 * n

A = 6 in^2 * 1600

A = 9,600 in^2

55? i think maybe

step-by-step explanation:

answer: if you weigh 60 pounds on earth, on the moon you will weigh about 10 pounds. if you weigh 120 pounds on earth, you will weigh about 20 pounds on the moon. since weight is caused by the mass of two objects that are near each other, the bigger the objects, the more the force of gravity.
