A postcard has an area of 24 square inches. Two enlargements of the postcard have areas of 54 square inches and 96 square inches
Alex777 [14]

Answer:

original is 4 & 6.

for 54 sq inch= 6 & 9 and for 96 sq inch=8 & 12

Step-by-step explanation:

Given: The length is 1.5 times the width.

so the length is, l = 1.5w ----(a)

lw = 24  =1.5w(w)

lw = 54= 1.5w(w)

lw = 96 =1.5w(w)

Further simplifying it,

1.5w^{2}=24

1.5w^{2}=54

1.5w^{2}=96

so,

w^{2} = \frac{24}{1.5}=16

w^{2}= \frac{54}{1.5} =36

w^{2}= \frac{96}{1.5} =64

taking the square root, we get:

w = 4

w = 6

w = 8

By putting the above values in eq (a), we can find their corresponding lengths:

l = 1.5(4) = 6

l = 1.5(6) = 9

l = 1.5(8) = 12

So a few lengths could be:

(l, w)

(6,4)

(9,6)

(12,8)

Please help I will give you Brainlest and 10 point's ​
Luba_88 [7]

a) To find the volume of a cube, you cube the side length.

So, that will be V = 9/2³ = 729/8 in³.

b) To find the volume of a rectangular prism, you multiply the length by the width by the height.

So, that is V = 18 * 9 * 9/2 = 729 in³.

c) To find how many times the smaller box can go into the larger one, you divide the larger one's volume over the smaller one's.

That is <em>729/(729/8) = 729*8/729 = </em><em>8 boxes</em><em>.</em>
