It’s 678m2 because Given the dimension of a rectangular prism l×b×h,its surface area is 2(lb+bh+lh)Hence surface area of a rectangular prism that measures 12 m x 11 m x9 mis 2×(12×11+11×9+12×9)= 2×(132+99+108)= 2×339=678m2

Answer:
12
Step-by-step explanation:
25% of what number is 3
25% goes into 100...4 times.
Then 4 times 3 equals to 12.
If you want to check, you would do 25% of 12.
and that would equal 3.
Add it tighter and it will make ur number then subtract that
It’s D because the opposite sides are congruent.
