Dmitri wants to cover the top and sides of the box shown with glass tiles that are 3 5 mm square How many tiles does he need 20

Anna35 [415]

Lets split the box in pieces and then add:
top = 20*15 = 300
sidesA = 2*20*9 = 360, is multiplied by 2 cause there are 2 sides like this
sidesB = 2*9*15 = 270, is multiplied by 2 cause there are 2 sides like this
so in total we have:
total = 300 + 360 + 270 = 930 cm^2
if we express this quantity in mm^2 we have:
1cm² = 100 mm²total = 930*100 = 93000 mm^2
so if the tiles are 5 mm^2 we need:
total tiles = 93000/5 = 18600
we need 18600 tiles of 5 mm^2

Gail is making costumes for a school play. Each rabbit costume needs one and one half yards of white fur fabric, a yard of blue

olga nikolaevna [1]

Answer:

Gail will need 12 yards of white fur, 8 yards of blue striped and 2 yards of the pink felt.

Step-by-step explanation:

We are given that,

The amount of yards for making one costume of different fabrics are,

White fur fabric = $1\frac{1}{2}$ = $\frac{3}{2}$ yards

Blue striped fabric = 1 yard

Pink felt for ears = $\frac{1}{4}$ yards.

So, we have,

The amount required to make 8 costumes are,

White fur fabric = $\frac{3}{2}\times 8$ = 3×4 = 12 yards

Blue striped fabric = 1×8 = 8 yards

Pink felt for ears = $\frac{1}{4}\times 8$ = 2 yards.

Thus, Gail will need 12 yards of white fur, 8 yards of blue striped and 2 yards of the pink felt.
