Total area is 8.7218.721 m^2m2 and volume is 0.085530.08553 m^3m3

Explanation:

Although it is considered a plate as its two dimensions (as length ll is 4.2344.234 mm and breadth bb is 1.0051.005 mm) are very large, but thickness tt is relatively much smaller at 2.012.01 cm.cm. i.e. 0.02010.0201 mm.

Hence volume is

lxxbxxt=4.234xx1.005xx0.0201=0.08553l×b×t=4.234×1.005×0.0201=0.08553 m^3m3.

and total surface area is

2(lb+lt+bt)2(lb+<+bt)

= 2xx(4.234xx1.005+4.234xx0.0201+1.005xx0.0201)2×(4.234×1.005+4.234×0.0201+1.005×0.0201)

= #2xx(4.25517+0.0851034+0.0202005)

= 2xx4.36047392×4.3604739

= 8.7209478~=8.7218.72094788.721 m^2m2
