Answer:

7\times 200+7\times 50+7\times 6

Step-by-step explanation:

We are asked to write an expression that shows the multiplication of 7\times 256 using expanded form and the distributive property.

First of all, we will write 256 in expanded form as:

256=200+50+6

Now, we will multiply 7 by (200+50+6) as:

7\times (200+50+6)

7\times 200+7\times 50+7\times 6

Therefore, our required expression would be 7\times 200+7\times 50+7\times 6.

What is the total surface area of the rectangular pyramid below
Novosadov [1.4K]

Answer:

<h2>S.A. = 225 ft²</h2>

Step-by-step explanation:

We have

the rectangle 12ft × 6ft

two triangles with the base b = 12ft and the height h = 8ft

two triangles with the base b = 6ft and the height h = 9.5ft.

The formula of an area of a rectangle l × w:

A=lw

Substitute:

A_1=(12)(6)=72\ dt^2

The formula of an area of a triangle:

A=\dfrac{bh}{2}

Substitute:

A_2=\dfrac{(12)(8)}{2}=48\ ft^2

A_3=\dfrac{(6)(9.5)}{2}=28.5\ ft^2

The Surface Area:

S.A.=A_1+2A_2+2A_3

Substitute:

S.A.=72+2(48)+2(28.5)=225\ ft^2
