Question

1) Find the height of a cuboid whose volume is 275 cm³ and base area is 25 cm².

​

Answer 1

Figure:-

$\setlength{\unitlength}{0.74 cm}\begin{picture}\thicklines\put(5.6,5.4){\bf A}\put(11.1,5.4){\bf B}\put(11.2,9){\bf C}\put(5.3,8.6){\bf D}\put(3.3,10.2){\bf E}\put(3.3,7){\bf F}\put(9.25,10.35){\bf H}\put(9.35,7.35){\bf G}\put(3.5,6.1){\sf z\:cm}\put(7.7,6.3){\sf y\:cm}\put(11.3,7.45){\sf x\:cm}\put(6,6){\line(1,0){5}}\put(6,9){\line(1,0){5}}\put(11,9){\line(0,-1){3}}\put(6,6){\line(0,1){3}}\put(4,7.3){\line(1,0){5}}\put(4,10.3){\line(1,0){5}}\put(9,10.3){\line(0,-1){3}}\put(4,7.3){\line(0,1){3}}\put(6,6){\line(-3,2){2}}\put(6,9){\line(-3,2){2}}\put(11,9){\line(-3,2){2}}\put(11,6){\line(-3,2){2}}\end{picture}$

base height = $\large\rm { lb}$

$\large\rm { V = lbh}$

$\large\rm { \therefore \ height =}$ Volume ÷ base area

= 275÷25

= 11 cm

So, height = 11 cm.

Answer 2

Answer:

11 cm

Step-by-step explanation:

we have volume of cuboid and base area.

so easily we can find it
