Volume:V=L%2AW%2Ah
Surface area:A+=+2WL+%2B+2Lh+%2B+2hW
1.
L=2.5
W=1.5
h=5
V=L%2AW%2Ah
V=2.5%2A1.5%2A5
V=18.75
A+=+2WL+%2B+2Lh+%2B+2hW
A+=+2%2A1.5%2A2.5+%2B+2%2A2.5%2A5+%2B+2%2A5%2A1.5
A+=+7.5+%2B+25+%2B+15
A+=+47.5+

2.
L=25%2F3
W=3
h=5%2F4
V=L%2AW%2Ah
V=%2825%2Fcross%283%29%29%2Across%283%29%2A%285%2F4%29
V=25%285%2F4%29
V=31.25
A+=+2WL+%2B+2Lh+%2B+2hW

A+=2%2A25+%2B+%2825%2F3%29%285%2F2%29+%2B+%285%2F2%293
A+=+50%2B20.83333333333333%2B7.5+
A+=+78.33333333333333+
A+=+78.3+
