Answer:

C

Explanation:

The surface area of a rectangular prism can be found using:

A=2(wl+hl+hw)

The length is 6 units, the width is 5 units and the height is 4 units. Substitute 6 in for l, 5 in for w, and 4 in for h.

A=2((5*6)+(4*6)+(4*5))

Multiply 5 and 6

A=2(30+(4*6)+(4*5))

Multiply 4 and 6

A=2(30+24+(4*5))

Multiply 4 and 5

A=2(30+24+20)

Add 30, 24 and 20

A=2(74)

Multiply 2 and 74

A=148

The surface area is 148 units^2. The answer is choice C.
