Dayson is covering a package in the shape of a rectangular prism with wrapping paper. The package is 50 centimeters by 20 centim
eters by 18 centimeters. He has 1 square meter of wrapping paper. Can he completely cover the package with wrapping paper? Use the drop-down menus to explain and show your answer. Dayson has 1 m2 of wrapping paper, which is cm2. The package has a surface area of cm2. The area of the package is the area of the wrapping paper. So, Dayson cover the package with the wrapping paper.
<span>Dayson has 1 m2 of wrapping paper, which is 10000 cm2: 1 m = 100 cm 1 m^2 = (100 cm)^2 </span>1 m^2 = 10000 cm^2 <span>The package has a surface area of cm2: A = 2*(50*20) + </span>2*(50*18) + 2*(18*20) A = <span>
<span>4520 cm^2 </span></span>The area of the package is less than the area of the wrapping paper (4520 cm^2 < 10000 cm^2<span>). So, Dayson cover the package with the wrapping paper.</span>
The correct question is <span>A rectangular prism with a volume of 2 cubic units is filled with cubes with side lengths of 1/4 unit. How many cubes does it take to fill the prism?
we know that [volume of the cube]=b</span>³ b=1/4 unit [volume of the cube]=(1/4)³------> 1/64 unit³
if 1 cube has a volume of ----------------> (1/64) unit³ x cubes--------------------------------> 2 unit³ x=2/(1/64)-----> x=2*64----> x=128 cubes
