Answer:

The surface area is 160 cm^2

Step-by-step explanation:

The formula for surface area of a rectangular prism is 2(lw + hl + hw)

lastbenchstudent

let l, b and h are length breadth and height of this prism.

so surface area is given by formula

SA = 2 ( lb + bh + hl)

here l = 10, b = 5 h = 2

so

SA = 2( 10×5 + 5×2 + 2×10)

= 2 ( 50+ 10 + 20)

= 2× 80

= 160 square cm
