Answer:
<em>1,172.5cm²</em>
Step-by-step explanation:
Total surface area of a box = 2(LW + WH + LH)
L is the length = 11.5cm
W is the width = 7cm
H is the height = 1.5cm
Substitute
TSA = 2(11.5(7) + 7(1.5) + (11.5)(1.5))
TSA = 2(80.5+10.5+17.25)
TSA = 2(117.25)
TSA = 234.5cm²
<em>Hence the total surface area of a stack of five such compact disc boxes will be 5(234.5) = 1,172.5cm²</em>
Answer:
A and D
Step-by-step explanation:
The sum is 1625.
Answer in Words: One thousand and six hundred twenty-five.
The cube of 10 is 1000.
10 X 10 = 100 (square of ten)
100 x 10 = 1000 (cube of ten)
The square of 25 is 625.
25 x 25 = 625 (square of 25)
Therefore, 1000 + 625 = 1625
the sum is 1625
Answer:
- (A)Six of the one-half cubes would have a volume of 3 cubic units.
- (D)Three of the one-third cubes will make 1 unit cube.
- (E)Two of the one-half cubes will make 1 unit cube.
- (F)Both stacks will have a volume of 3 cubic units.
Step-by-step explanation:
Marissa claims that stacking 6 blocks with dimensions of
will give the same volume as stacking 9 blocks with dimensions of
.
First, let us examine the volume of each of the blocks.
<u>For Block 1</u>
The dimensions are:

Volume of 1 block = 
Volume of 6 blocks of dimension

<u>For Block 2
</u>
The dimensions are:
Volume of 1 block =
Volume of 9 blocks of dimension
The following statements out of Marissa's claim are true:
(A)Six of the one-half cubes would have a volume of 3 cubic units.
(D)Three of the one-third cubes will make 1 unit cube.

(E)Two of the one-half cubes will make 1 unit cube.

(F)Both stacks will have a volume of 3 cubic units.
