Hope you know that formula for volume of a cube is area of base time height
and volume of a square pyramid is area of base time height divide 3
- so in this your exercise case we know that area of cube is 36 cm^3 what is area of base time height
- so this mean that the volume of a square pyramide what can fit perfectly inside the cube will be equal 36/3 = 12 cm^3

Answer:

$\text{The volume of square pyramid is}12cm^3$

Step-by-step explanation:

Given a cube with a volume of 36 cubic centimeter. we have to find the volume of square pyramid that can fit perfectly inside the cube.

As the pyramid base is same as the side of cube

$\text{Volume of cube is }a^3$

$\text{Volume of square pyramid is=}\frac{a^3}{3}$ (∵a=h)

i.e the volume of square pyramid is one-third of the volume of cube.

∴ $\text{Volume of square pyramid is=}\frac{1}{3}\times\text{Volume of square pyramid}$

$=\frac{36}{3}=12cm^3$

Hence, $\text{the volume of square pyramid is}12cm^3$

Henry's wage is £450 per week.

marishachu [46]

Answer:

He saves £135 each week

Step-by-step explanation:

He spends 2/5 of his wage on food

2/5x450=£180

He spends 180£ on food each week

30% of 450 is 135 which he spends on house holdbills. thus, he pays £135 on bills

so his total expenditure is 135+180= £315

he saves the rest which is £135.

thus, your answer is £135

The rectangle below has an area of x^2-x-72x 2 ?x?72 square meters and a length of x+8x+8 meters. What expression represents the

Varvara68 [4.7K]

Answer:

Area of the rectangle is given by:

$A = l \times w$

where

A is the area of the rectangle

l is the length of the rectangle

w is the width of the rectangle respectively.

As per the given statement:

Area of the rectangle(A) = $x^2-x-72$ square meters

length of the rectangle(l) = x+8

Substitute these in the given formula we have;

$x^2-x-72 = (x+8) \times w$

$x^2-9x+8x-72 = (x+8) \times w$

$x(x-9)+8(x-9)= (x+8) \times w$

or

$(x+8)(x-9)= (x+8) \times w$

Divide both sides by x+8 we have;

$w = (x-9)$ meters.

Therefore, the expression represents the width of the rectangle is x-9 meters
