I give 20 score! Find the volume

381

Step-by-step explanation:

Lets solve this in two parts, first the bottom one, then the upper one

Bottom one is a rectangle so 3*7*16=336

The one above is a triangular prism or something. You use base times height to find it. The base is 3*5/2=7.5

7.5 times height of 6 is 45.

Now add the 2 together to get 381

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.
