Surface area of the prism is 2xy+2xz+2yz
I think, we can cut hole on the face of the prisma 40x30, and size of the whole will be 5X5X5
hole increases surface area. If side of the cube is "a", then a^2 is the area of the one face of the cube.
when we are doing the hole, we remove 2 faces and add 4 more faces, so
2xy+2xz+2yz-2a^2+4a^2= 2xy+2xz+2yz+2a^2
So, 2*5*40+2*5*30+2*40*30+2*5^2=3150 cm^2
i hope it helps, it is what i can come up with now
Answer:
A. 2^4*5 B. 3^3*2
Step-by-step explanation:
80/2 = 40
40 and 2
20 and 2
10 and 2
5 and 2
So we got 4 2's and one 5 bcz they prime.
27 and 2
9 and 3
3 and 3
So 2 3's and one 2 bcz they prime.
To find the volume of a box-shaped fish trap, we have to multiply the three dimensions of it:
(1/4 m)* (2/3 m)* (3/5 m)
= (1*2*3)/ (4*3*5) m^(3)
= 6/ 60 m^(3)
= 1/10 m^(3)
= 0.1 m^(3)
The volume of the box-shaped fish trap is 0.1 m^(3).
Hope this is helpful~
Answer: 24c
Step-by-step explanation:
c = cost
6x4=24
24 times the amount it costs per hour c
24c
