set f(x) equal to y
y = 19/ x^3
swap x and y
x = 19/y^3
make y the subject
xy^3 = 19
y^3 = 19/x
then just replace y with f^-1(x)
hope this helped! have a good day ~ •lipika•

Answer:
G. 7600
Step-by-step explanation:
Step 1: Deconstruct the shape
2 rectangles with dimension of 50 cm x 20 cm
2 rectangles with dimension of 40 cm x 20 cm
2 rectangles with dimension of 40 cm x 50 cm
Step 2: Find surface area of the shapes
2(50 x 20) = 2000
2(40 x 20) = 1600
2(40 x 50) = 4000
Step 3: Add the surface areas together
2000 + 1600 + 4000 = 7600
Therefore the surface area is 7600 and the answer is G.
