Total area is 8.721 m^2 and volume is 0.08553 m^3

Explanation:

Although it is considered a plate as its two dimensions (as length l is 4.234 m and breadth b is 1.005 m) are very large, but thickness t is relatively much smaller at 2.01 cm. i.e. 0.0201 m.

Hence volume is

lxxbxxt=4.234xx1.005xx0.0201=0.08553 m^3.

and total surface area is

2(lb+lt+bt)

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

= #2xx(4.25517+0.0851034+0.0202005)

= 2xx4.3604739

= 8.7209478~=8.721 m^2
