Answer:
If you solve for a2+b2=c2 you will see
Step-by-step explanation:
1 will be 11.61
2. Will be 7.6
so there will be a 4.01 difference
1. a2+3(2)=12(2)
a2+9=144
then subtract 9 from 144
you get 135
then
135

Answer:
480 inches^3
Step-by-step explanation:
The volume of a Prism is: Bh
B= length of the base
h= height of the lateral face
(8*10)4
320 inches^3
So for the 2nd figure on top you do the same.
This time you divide by 2.
So it's 160 inches^3.
Add up you get a sum of 48- inches^3.
Or 480 cubic inches.
I think it is D, Hope this helps!
Answer:
3,216 cm²
Step-by-step explanation:
The question is asking the surface area of a rectangular prism with the given dimension. That area is the sum of the areas of the 6 faces of the prism. Since opposite faces have the same area, we only need to compute 3 areas, then double the sum of those:
S = 2(LW +LH +WH)
This can be made a little easier to compute by some factoring:
S = 2(LW +H(L +W))
It does not matter which dimensions are designated length (L), width (W), or height (H).
__
S = 2((24 cm)(54 cm) +(4 cm)(24 cm +54 cm))
= 2(1296 +4(78)) cm² = 2(1608) cm²
S = 3216 cm²
The surface area of Emma's rectangular box is 3216 square centimeters.
