Answer:
A =62x^2
Step-by-step explanation:
The formula for surface area of a rectangular prism is given by
A=2(wl+hl+hw)
Given a width of 2x and length of 3x and a height of 5x, substitute into the equation
A = 2(2x*3x+ 5x*3x+ 2x*5x)
A = 2(6x^2 + 15x^2 +10x^2)
Combine like terms
A = 2(31x^2)
A =62x^2
1) x=1
2) x=2.9
3) x=-10
4) x=?
