An artist wants to make alabaster pyramids using a block of alabaster with a volume of 576 cubic inches. She plans to make each

LenaWriter [7]

Pyramid
volume=base area times height times 1/3
or
length times widht times height times 1/3
base area=3
3 times height iems 1/3
height=4
3 times 3 times 1/3=4 times 1/3 times 3=4 times 1
each pyramide=4 in volume
so
x pyramids =alabaster volume
divide by pyramids
x=alabaster/pyrimds
alabaster=576
pyramids=4
divide
576/4=144
the artis can make 144 pyramids

The width of a rectangle is equal to m cm, but it’s length is five times greater than the width. Find the area of the rectangle.

Irina18 [472]

Area of rectangle is $5m^{2}\ cm^{2}$

Step-by-step explanation:

Given,

Width of rectangle = m cm

As length is 5 times more than width;

Length of rectangle = 5m cm

Area of rectangle = Length x Width

$Area\ of\ rectangle = 5m*m\\Area\ of\ rectangle = 5m^{2} \\As\ length\ and\ width\ both\ are\ in\ cm\,\ therefore\\Area\ of\ rectangle = 5m^{2}\ cm^{2}$

Area of rectangle is $5m^{2}\ cm^{2}$
