How many 1/2 inch cubes does it take to fill a box with a width of 3 1/2 inches, length of 2 inches and height of 5 1/2 inches?

Answers

Answer:

Step-by-step explanation:

Remark

I'm going to assume that the edges of the cubes are 1/2 inch on each side.

V = 1/2 * 1/2 * 1/2 = 1/8 cubic inches.

Volume of the box

V = L * w * h

Givens

L = 2 inches

w = 3.5 inches

h = 5.5 inches

Solution

V = L * w * h

V = 2 * 3.5 * 5.5

V = 38.5

1/8 has the decimal equivalent value of 0.125

Number of cubes needed = Volume of the box / volume of the cube

Number of cubes needed = 38.5 / 0.125

Number of cubes needed = 308

Step-by-step explanation:

The size of angle x is 25°.

What is a Triangle?

A triangle in geometry is a three-sided polygon with three edges and three vertices. The fact that a triangle's internal angles add up to 180 degrees is its most crucial characteristic. This characteristic is known as the triangle's angle sum property.

As per the given data:

The two external angles are given in the diagram.

Assume angles as ∠1, ∠2 and ∠x in anti-clockwise order.

For finding the angles of the triangle:

∠1 + 105° = 180° {linear pair angles}

∠1 = 75°

∠2 + 140° = 180° {linear pair angles}

∠2 = 80°

Using angle-sum property of a triangle:

∠1 + ∠2 + ∠x = 180°

75° + 80° + ∠x = 180°

∠x = 25°

Hence, the size of angle x is 25°.
