Question

I NEED HELP PLSSS , what is the volume and surface area

Answer 1

Given:

The dimensions of the given cuboid are 8 in, 6 in and 7 in.

To find:

The volume and the surface area of the given cuboid.

Solution:

The volume of cuboid is:

$V=l\times b\times h$

Where, l is length, b is breadth and h is height.

$V=8\times 6\times 7$

$V=336$

Therefore, the volume of the cuboid is 336 cubic inches.

The surface area of the cuboid is:

$A=2(lb+bh+hl)$

Where, l is length, b is breadth and h is height.

$A=2(8\times 6+6\times 7+7\times 8)$

$A=2(48+42+56)$

$A=2(146)$

$A=292$

Therefore, the surface area of the cuboid is 292 square inches.
