The base of an open rectangular box is of length (2x + 5) cm and width x cm. The area of this base is 58 cm
The height of the open box is (x - 2) cm.
a) Show that 2x + 5x -58 = 0
) Solve the equation 2x + 5x -58 = 0, giving your answers correct
to 2 decimal places
D) Hence calculate the volume of the box, stating the units of your answer.

a) x = 8.29 cm

D) V = 1125.27 cm³

Step-by-step explanation:

a) We can solve the equation as follows:

D) The volume of the box is given by:

Where:

l: is the length

w: is the width

h: is the height

The length of the rectangular box is:

The width is x = 8.29 cm.

And the height is:

Hence, the volume is:

8

step-by-step explanation:

just put √(2) * √(32) into a calculator. that will make the answer be 8.

the 8 in 8,420 is in the thousands place so it's value is 8 thousand.

the 8 in 6,870 is in the hundreds place so it's value is 8 hundred.

divide 8000 by 800 to find the answer:

8000 / 800 = 10

the 8 in 8,420 is 10 times greater than the 8 in 6,870
