Answer:
1326 cm²
Step-by-step explanation:
1) Identify the equation of the surface area of a rectangular prism
2) Input the corresponding values ;
; and
into the equation, and solve for the area
3) ∴
y = - 3
Since y varies directly as x then
y = kx ← ( k is the constant of variation )
to find k use y = - 1 when x = 3
k = =
= -
hence y = - x
when x = 9, then
y = - × 9 = - 3
