Question

The whole surface area of a cuboid is 214 cm^2 and volume is 210 cm^3 and the based area is 42 cm^2 find Italian edges

Answer 1

TSA OF CUBOID = 214 CM^2
VOL. OF CUBOID = 210 CM^3
BASE AREA OF CUBOID or lb= 42 CM^3
H=VOLUME/BASE AREA
H = 210/42
H = 5 cm

Answer 2

Answer:

The edges are 6 , 7 and 5

Step-by-step explanation:

The based area is $42 cm^2$

So, $Length \times Breadth = 42$

$Breadth = \frac{42}{Length}$

Volume of cuboid = $length \times Breadth \times Height$

$210=42 \times Height$

$\frac{210}{42}=Height$

$5=Height$

Total surface area of cuboid = $2(lb+bh+hl)$

$214=2(42+5\frac{42}{l}+5l)$

$l = 6,7$

When length = 6

$Breadth = \frac{42}{6}=7$

When length = 7

$Breadth = \frac{42}{7}=6$

Hence the edges are 6 , 7 and 5
