Answer:

[tex]SA=\frac{1}{2}(5)(12)+\frac{1}{2}(5)(12)+(5)(10)+(12)(10)+(13)(10)[/tex]

Step-by-step explanation:

we know that

The surface area is equal to the area of all the faces of the triangular prism

[tex]SA=\frac{1}{2}(5)(12)+\frac{1}{2}(5)(12)+(5)(10)+(12)(10)+(13)(10)[/tex]

simplify

[tex]SA=(5)(12)+(5)(10)+(12)(10)+(13)(10)[/tex]

[tex]SA=360\ cm^{2}[/tex]

Answer:

Surface of the area =  (10 × 13) + (10 × 12) + (10 × 5) + 2[1/2 × 12 × 5]

Step-by-step explanation:

Surface area of the rectangular prism can be calculated by

Total surface area = area of rectangle with dimensions 10 cm × 13 cm +

area of rectangle with dimensions 10 cm × 12 cm +

area of rectangle with dimensions 10 cm × 5 cm +

area of two similar triangle with height 12 cm and base 5 cm.

= ( 10 × 13 ) + ( 10 × 12 ) + ( 10 × 5 ) + 2[1/2 × 12 × 5]

Surface of the area =  ( 10 × 13 ) + ( 10 × 12 ) + ( 10 × 5 ) + 2[1/2 × 12 × 5]
