  • A rectangular cube of iron is a side 8 cm.
  • Given, side (a) = 8 cm.
  • We know, volume of a cube =  {a}^{3}
  • Therefore, the volume

=  {8}^{3}  \:  \: cm ^{3}  \\  = 512 \:  \:  {cm}^{3}

<u>A</u><u>nswer</u><u>:</u>

<u>The </u><u>volume </u><u>is </u><u>5</u><u>1</u><u>2</u><u> </u><u>cube </u><u>centimetres</u><u>.</u>

Hope you could get an idea from here.

All the 5 angles are equal to 286, so....
360 - 286 = 74
then,

Varvara68 [4.7K]

Answer:

\triangle BOT \cong \triangle IEW

Step-by-step explanation:

We are given the following in the question:

\angle BTO \cong \angle IWE\\WI \cong BT\\OT \cong EW

We have to prove:

\triangle BOT \cong \triangle IEW

Proof:

\text{In }\triangle BOT \text{ and } \triangle IEW

we can write:

\angle BTO = \angle IWE\text{ (Given)}\\WI \cong BT\text{ (Given)}\\OT \cong EW\text{ (Given)}

Hence, the two triangle are congruent by SAS congruency rule.

\triangle BOT \cong \triangle IEW

The attached image shows the two triangle.
