Question

Jordan made a wooden square box. All sides of the wooden box are 6cm. If he wants to increase the length of all sides by 1.6 cm, what will be the perimeter and area of the new box?

Answer 1

The perimeter of the square wooden box is 91.2 cm

Area of the square wooden box is 346.56 sq. cm

Explanation:

The original side of the wooden box = 6 cm

Now, New side of the box = Original side of the square + 1.6 cm

= 6 cm + 1.6 cm = 7.6 cm

or, the new side of the wooden square box = 7. 6 cm

(a) PERIMETER of the new box = 12 x Side of the box

= 12 x (7.6 cm) = 91.2 cm

Hence, the perimeter of the square wooden box = 91.2 cm

(b) Area of the new box = 6 x
`(Side)^2`

= 6 x
`(7.6)^2` = 346.56 sq. cm

Hence, the area of the square wooden box = 346.56 sq. cm
