A restaurant needs a block of ice that is exactly 480 cubic inches in volume. The height of the ice block must be 10 inches.

7x8x10

Step-by-step explanation:

there are lots of possible answers, ranging from 1x48x10 to 7x8x10. I'm thinking there must be another data point to determine it more precisely.

given that triangle abc is transformed two times to get triangle

a"b"c"

first abc is transformed in to a'b'c' as follows:

the coordinates of a are (1,-1) and transformed into a'(-1,1)

similarly b (4,-2) became b'(-4,2) and

c(7,-2) became c'(-7,2)

i.e. (x,y) becomes (-x,-y)

this is nothing but reflection about a point here origin.

thus first transformation is reflection on the origin.

next is exactly shifting 3 units down
