If the dimensions were all the same number ... the box was a cube ...
then each dimension would be (the cube root of 13,800) cm.
∛13,800 = 23.986... (rounded)
so the place to look is around 23 .
(22 x 23 x 24) = 12,144 <== too small; go up one integer
(23 x 24 x 25) = 13,800 <== Eureka !
The consecutive integers are 23, 24, and 25 .
Ok so I assume
28 and decreased by 12.5%
percent means partst out of 100 so
12.5%=12.5/100=0.125
first find 12.5% of 28 then subtract
0.125 times 28=3.5
decrease
28-3.5=24.5
answer is 24.5
B. If you were to solve for x, the values would be x=1.5275 and x=-1.5275.
The wall has a shape of trapezium, the area will therefore be given by:
A=1/2(a+b)*h
where a and b are the side length, h is height:
a=25, b=15, h=40
thus the area of the wall will be:
A=1/2(25+15)×40
A=1/2×40×40
A=800 ft²
Answer: Area=800 ft²
Step-by-step explanation:
can you elaborate on this problem a bit more? I just want to give you an accurate anwser
