Question

Hodi is buliding a birdhouse.Each if the four walls of the birdhouse needs to be 5.5 inches long.Hodi gas a piece of board that is 24.5 inches long.Is the board that is 24.5 inches long.Is the board long enough to be cut inti the four walls of the birdhouse?Estimate using compatible numbers.

Answer 1

Yes the board which is 24.5 inches long is enough to build the bird house which requires 24 in to build the same.

Explanation:

Given:

Hodi is building bird house.

bird house consist of 4 walls.

Each wall needs to be of 5.5 in.

Hodi has board = 24.5 in.

Now we need to estimate using compatible numbers.

The compatible number for 5.5 in. is 6 in.

First we will find the total board required to build bird house.

total board required is equal to Number of walls in house multiply by length of each wall.

Total board required =
`\textrm{Number of walls} * \textrm{length of each wall} = 4 * 6 =24 in.`

Total board required = 24 inches.

Board he has = 24.5 inches.

Hence 24.5 in. will be enough to build the bird house which requires 24 in.
