Answer with Step-by-step explanation:
The given figure is a cuboid.
We know that surface area(S) of cuboid is given by:
S=2(lb+bh+hl)
Where l is the length, b is the breath and h is the height
Here, l=12 mm
b=6 mm
and h=(7+2) mm=9 mm
Surface Area= 2(12×6+6×9+9×12)
=2(72+54+108)
= 2×234
= 468 mm²
Hence, Correct option is:
C. 468 mm squared
Valume= 13x(3.1415926536)x(5cm)^2 x (10cm)= 10210.18cm^3
The answer 81pi is if it asked you to keep the answer in terms of pi.
The second answer is if they wanted pi calculated into the answer.
