If a candy box has a base which is 10 cm long and 8 cm wide, with a height of 5 cm, find out how much cardboard is needed to make the box.

400cm³ of cardboard is required to make the box

Step-by-step explanation:

Hello,

To find the the size of cardboard required to make the box we need to know the shape of the box. This is to enable us calculate the volume of the box.

Data;

Length = 10cm

Width = 8cm

Height = 5cm

This dimension corresponds to that of a cubiod.

Volume of a cubiod = length × width × height

Volume of the box = 10 × 8 × 5

Volume of the box = 400cm³

The volume of the box is 400cm³

About 400cm³ of cardboard is needed to make the box

x = 2

step-by-step explanation:

if sr parallel to ba then the sides bc and ac are in proportion, that is

= ← substitute values

= ( cross- multiply )

27x = 6(4x + 1)

27x = 24x + 6 ( subtract 24x from both sides )

3x = 6 ( divide both sides by 3 )

x = 2
