Question

There are two containers, a cube with side 7cm and the other a cylinder with radius 7cm and height 7cm.which container has larger surface area?​

Answer 1

Answer:

Let's find out

Surface Area of Cube =

$6 \times 7 \times 7 = 49 \times 6 = 294 \: cm {}^{2}$

Surface Area of Cylinder =

$2\pi \: rh \: + 2\pi \: r {}^{2}$

So now

$(2 \times \frac{22}{7} \times 7 \times 7) + (2 \times \frac{22}{7} \times 7 \times 7) = 308 + 308 = 616 \: cm {}^{2}$

Here we see Cylinder has more surface Area
