Answer 1

A = 94 square cm

Explanation:

Surface Area of a Closed Box

The surface area of a rectangular prism of dimensions x, y, and z is given by:

A = 2(xy + yx + xz)

The dimensions of a closed box (a rectangular prism) with dimensions x=3 cm, y=5 cm, and z=4 cm is:

A = 2(3*5 + 5*4 + 3*4)

Calculating:

A = 2(15 + 20 + 12)

A = 2(47)

A = 94 square cm
