Which rectangular prism has a surface area of 56 square units? [Note: Art is not drawn to scale.] A rectangular prism with a length of 5, width of 3, and height of 1. A rectangular prism with a length of 2, width of 2, and height of 6. A rectangular prism with a length of 5, width of 3, and height of 2. A rectangular prism with a length of 6, width of 2, and height of 4.

The rectangular prism with a length of 2, width of 2, and height of 6 has a surface area of 56 sq. units.

Step-by-step explanation:

The surface area of a rectangular prism is equal to the sum of the three lateral surfaces, multyplied then by a factor of 2. One surface is the product of the length and the width, the other is the product of the length and the height, and the last is the product of the width and the height.

If l: length, w: width and h: height, we can express the surface area as:

A rectangular prism with a length of 5, width of 3, and height of 1.

A rectangular prism with a length of 2, width of 2, and height of 6.

A rectangular prism with a length of 5, width of 3, and height of 2.

A rectangular prism with a length of 6, width of 2, and height of 4.

check the picture below.

well, the angle at the vertex d is clearly not a right-angle, let's check for the one at the vertex f which does look like,   however if it's indeed, that means ef is perpendicular to df, in which case their slopes will be negative reciprocal of each other.

so the negative reciprocal of the slope of ef is 1, however the slope of df is not 1, is 1/2, so nope, they're not perpendicular lines.

3x + 18 = 147°

step-by-step explanation:

3x + 18 = 147°, because the value of the central angle is equal to the value of the arc formed by it.

i hope i you.
