The rectangular prism shown below has a length of 6 units, width of 5 units, and a height of 4 units.
What is the surface area of the prism?
A. 88 square units
B.60 square units
C. 148 square units
D. 120 square units

C

Step-by-step 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.

it's equivalent, so we can say that its equal.

let's call the denominator x and the numerador is 18 less then denominator, x - 18.

multiply

2.x = 5.(x - 18)

2x = 5x - 90

90 = 5x - 2x

90 = 3x

x = 90/3

x = 30

so:
