the surface area of the prism is [tex]234mm^2[/tex] .
Step-by-step explanation:
Here we have , A right rectangular prism has a length of 15 millimeters, width of 3 millimeters, and height of 4 millimeters. We need to find What is the surface area of the prism . Let's find out:
We know that surface area of the prism = [tex]2(lb+bw+wl)[/tex] . According to question we have following parameters as :
[tex]length = 15 mm\\width=3mm\\height=4mm[/tex]
Putting these values to find area of prism we get:
⇒ [tex]Area = 2(lw+wh+hl)[/tex]
⇒ [tex]Area = 2(15(3)+3(4)+4(15))[/tex]
⇒ [tex]Area = 2(45+12+60)[/tex]
⇒ [tex]Area = 2(117)[/tex]
⇒ [tex]Area = 234mm^2[/tex]
Therefore , the surface area of the prism is [tex]234mm^2[/tex] .
