Fudgin [204]

Answer:

35.9 units cubed

Step-by-step explanation:

Hello There!

The figure shown is a rectangular prism

The formula for volume of a rectangular prism is

Length times width times height

The dimensions for the shown figure are given

height = 4 1/2

length = 2 1/8

width = 3 3/4

given this information we just plug it in to the formula

so

V=3\frac{3}{4}*4\frac{1}{2} *2\frac{1}{8}

then we plug it in to a calculator and get that the volume is equal to

35.859375

finally we round to the nearest tenth and get that the volume is equal to

35.9 units cubed

Emily has a rectangular deck in her backyard with an area of 96 square feet. She wants to increase.
Dominik [7]

Answer:

The area of the deck after she doubles the length and width will be of 384 square feet.

Step-by-step explanation:

Area of a rectangle:

The area of a rectangle of length l and width w is given by:

A = lw

Doubling length and width:

If we double the length and the width, the dimensions are 2l and 2w. Thus, the area will be of:

A_d = 2l*2w = 4lw

That is, if both dimensions are doubled, the area is multiplied by 4.

What will the area of the deck be after she doubles the length and width?

Was 96. Then, both dimensions were doubled, and the area has to be multiplied by 4.

96*4 = 384

The area of the deck after she doubles the length and width will be of 384 square feet.
