Acube consists of twenty-seven 2×2×2-inch small cubes. all four of the corner cubes on the edge of the top layer fell off. which statement is true about the surface area of the resulting solid?
1. it is 32 cubic inches less than the surface area of the original cube.
2. it is 32 square inches greater than the surface area of the original cube.
3. it is 32 square inches less than the surface area of the original cube.
4. it is the same as the surface area of the original cube.

its the same surface area ad the orginal cube

Step-by-step explanation:

if youre on ttm

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:

54 kilometers per hour

step-by-step explanation:

according to rules:

1 km = 1000 meter

which means that 1 meter = 1/1000 km

1 hour = 3600 second [ as 1 hour = 60 min = 60 *60 seconds ]

which means that 1 second = 1/3600 hour

therefore, 1 kilometer/hour =

thus to convert 15 meter per second to kilometer per hour, we multiply 15 to 3.6 kilometer/hour.

15 meter/second=   which is the required answer.
