7 inches high, 4 inches long, and 4 inches wide what is the area

16 inches is area

Step-by-step explanation:

A = 144 square inches

Step-by-step explanation:

surface area of rectangular prism :

A = 2(hℓ + ℓw + hw)

A = 2(7 · 4 + 4 · 4 + 7 · 4)

A = 2(28 + 16 + 28)

A = 2(72)

A = 144 square inches

56.6

step-by-step explanation:

the ratio of the perimeters is equal to the scale.

the ratio of the areas is equal to the square of the scale.

34 / 20 = k

a / 19.6 = k²

substituting:

a / 19.6 = (34 / 20)²

a = 19.6 (34 / 20)²

a ≈ 56.6
