The ratio of the number of volleyball to the number of basketballs in the P.E room is 4:7 .there are 21 basketballs . How many v
marin [14]
Let volleyball be v and let basketball be b.

v : b = 4 : 7,      b = 21

v : 21 = 4 : 7

v/21 = 4/7

7*v = 4*21

v = 4*21/7

v = 4*3

v = 12

Volleyballs are 12

Hope this helps.

A card board box has a volume of 60 cubic feet give four different set of measurements that could be the dimension of the box
Fofino [41]

<em><u>Give four different set of measurements that could be the dimension of the box are:</u></em>

(l, w, h) = (2 , 15 , 2) feet and (2, 6, 5) feet and (2, 10, 3) feet and (3, 5, 4) feet

<em><u>Solution:</u></em>

Given that,

A card board box has a volume of 60 cubic feet

Cardboard box is of shape rectangular prism

<em><u>The volume of rectangular prism is given as</u></em>:

\text{Volume of rectangular prism } = l \times w \times h

Where,

l is the length

w is the width

h is the height

From given,

v = 60 cubic feet

60 = l \times w \times h

Give four different set of measurements that could be the dimension of the box:

Put l = 2 ; w = 15 ; h = 2

Then,

60 = 2 x 15 x 2

60 = 60

Put l = 2 ; w = 6 ; h = 5

60 = 2 x 6 x 5

60 = 60

Put l = 2 ; w = 10 ; h = 3

60 = 2 x 10 x 3

60 = 60

Put l = 3 ; w = 5 ; h = 4

60 = 3 x 5 x 4

60 = 60

Thus, give four different set of measurements that could be the dimension of the box are:

(l, w, h) = (2 , 15 , 2) feet and (2, 6, 5) feet and (2, 10, 3) feet and (3, 5, 4) feet
