Answer 1

Answer:

Surface area of the rectangular prism = $234\,mm^2$

Step-by-step explanation:

The surface area of the rectangular prism is:

$=2((Length\times Width)+(Width\times Height)+ (Height\times Length))$

$Length=15\,mm\\ \\Width=3\,mm\\\\Height=4\,mm$

Area is:

   $=2((15\times 3)+(3\times 4)+ (4\times 15))\\\\=2(45+12+60)\\\\=2(117)\\\\=234\,mm^2$

Surface area of the rectangular prism is: $234\,mm^2$
