What is the surface area of a number cube on which each edge has a length of 11 millimeters? (Hint: On a cube, the length, width, and height have the same measure.)

726 mm2
1331 mm2
242 mm2
132 mm2

no choice

Step-by-step explanation:

A=L*w,

Since L=w=h in the given

A=11mm*11mm=121mm*2

35-60 students are taking math.

answer: first option i.e. 'a' is correct.

step-by-step explanation:

since we have given that

number of minutes to wrap a small gift box = 4 minutes

we need to find the number of gifts to be wrapped in 5 minutes

since there is a direct variation, as the number of minutes will increase with   number of gifts to be wrapped.

so, let the number of gifts to be wrapped in 5 minutes be x.

so, it becomes,

hence, first option 'a'   is correct.
