A cuboid with a volume of 924cm3 has dimensions
4cm , (x+1)cm,( x+11)cm
show clearly that x2+112x-220=0
solve the equation by factorisation, making sure you show the factorisation
state both values of x
finally , find the dimension of the cuboid

4cm, 11cm, and 21cm

Step-by-step explanation:

The given dimensions of the cuboid are:

4cm , (x+1)cm,( x+11)cm

The volume of the cuboid is given as 904cm³

We know volume of a cuboid is given as:

V=LBH

We substitute the dimensions to get:

Divide through by 4.

We expand on the left to get:

This simplifies to:

To factor this expression we obtain:

But the dimension must be positive:

hence x=10

Therefore the dimensions are 4cm, 11cm, and 21cm

6,250

step-by-step explanation:

to get the area, multiply 360 by 160.(57,600)

to find out how many bags of fertilizer it will take, first figure out how many square feet one bag can hold. divide 1000 by 8(125) to get the unit rate(how many square feet one pound of fertilizer can hold)and multiply it by 50(6250). if i haven't made a mistake, that is the answer.
