Answer:
As Per Provided Information
Dimensions of rectangle prism are 3 cm , 4 cm and 10 cm .
We have been asked to determine it's surface area.
[tex] \underline{\boxed{\bf \: Surface \: Area_{(Rectangular \: Prism)} = 2(lw + hl + hw}}[/tex]
where,
w denote width
h denote height
l denote length
[tex] \longrightarrow\sf \: Surface \: Area_{(Rectangular \: Prism)} = \: 2(3 \times 4 + 4 \times 10 + 10 \times 3) \\ \\ \\ \longrightarrow\sf \: Surface \: Area_{(Rectangular \: Prism)} = \:2(12 + 40 + 30) \\ \\ \\ \longrightarrow\sf \: Surface \: Area_{(Rectangular \: Prism)} = \:2(82) \\ \\ \\ \longrightarrow\sf \: Surface \: Area_{(Rectangular \: Prism)} = \:164 \: {cm}^{2} [/tex]
Therefore,
Answer:
Surface area of rectangular prism is 164cm²
Step-by-step explanation:
Given :-
To find:-
Solution:-
Surface area of rectangular prism :-
2(lb + bh + hl)
putting the known values ,
Surface Area = 2(3×4+4×10+10×3) cm²
Surface area = 2(12+40+30) cm³
Surface area = 164cm²
