Answer:

A) 684 in^2

Step-by-step explanation:

Since it needs to be painted all around the box we have to find the surface area of the box

The surface area of cuboid is

=2lw+2lh+2hw (l: length, w: width, h: height)

=2×15×12+2×6×15+2×6×12

= 684 in^2

An irregular parallelogram rotates 360° about the midpoint of its diagonal. How many times does the image of the parallelogram c

Ad libitum [116K]

Answer:

The correct options is A.

Step-by-step explanation:

The each diagonal of an irregular parallelogram divides the parallelogram in two equal and congruent parts. The diagonal bisects each other.

It means, if a irregular parallelogram rotates 180° about the midpoint of its diagonal, then the image of the parallelogram coincide with its preimage during the rotation.

If a irregular parallelogram rotates 360° about the midpoint of its diagonal, then the image of the parallelogram coincide 2 times with its preimage during the rotation.

Therefore the correct option is A.
